ON WRIT OF CERTIORARI TO THE COURT OF APPEALS 

Appeal from Lancaster County 

R. Knox McMahon, Circuit Court Judge 

Opinion No. 27898 

Heard March 29, 2018 – Filed June 26, 2019 

REVERSED AND REMANDED 

Appellate Defender Susan Barber Hackett, of Columbia, 

for Petitioner. 

Attorney General Alan McCrory Wilson and Senior 

Assistant Deputy Attorney General Deborah R.J. Shupe, 

both of Columbia, for Respondent. 

CHIEF JUSTICE BEATTY: A Lancaster County jury found Kenneth 

Campbell met the statutory definition of a sexually violent predator (SVP) under 

South Carolina's SVP Act, S.C. Code Ann. §§ 44-48-10 to -170 (2018). Campbell 

appealed, and the court of appeals affirmed. In re Care & Treatment of Campbell, 

Op. No. 2016-UP-198 (S.C. Ct. App. filed May 11, 2016). On certiorari, Campbell 

contends the court of appeals erred in affirming his civil commitment because the 

State inappropriately impeached the credibility of Campbell's expert witness by 
 

 

 

introducing evidence of a recent arrest warrant for an unrelated sex offender whom 

the expert had opined was unlikely to reoffend. We find the admission of testimony 

about a mere arrest warrant of an unrelated individual in a collateral matter unduly 

prejudiced Campbell and, therefore, reverse and remand for a new commitment 

proceeding. 

I. Factual / Procedural History 

The State referred Campbell to the SVP program due to his four alleged sexual 

assaults of three minor children with whom Campbell slept in the same house. For

two of the assaults, the four-year-old victims recanted, and the State either dropped 

the charges or declined to press charges. For the remaining two assaults, one of 

which was committed while Campbell was out on bond for the other, Campbell 

entered an Alford1 plea to criminal sexual conduct with a minor in the first degree 

(CSCM-1st) and pled no contest to committing a lewd act on a child under the age 

of sixteen. He received an aggregate sentence of twenty years' imprisonment, 

suspended upon the service of twelve years' imprisonment and three years'

probation. 

Prior to Campbell's release, the State filed a petition pursuant to the SVP Act 

seeking Campbell's civil commitment for long-term control, care, and treatment. See 

S.C. Code Ann. § 44-48-30(1) (defining an SVP as "a person who: (a) has been 

convicted of a sexually violent offense; and (b) suffers from a mental abnormality 

or personality disorder that makes the person likely to engage in acts of sexual 

violence if not confined in a secure facility for long-term control, care, and 

treatment"). The trial court made a determination of probable cause and appointed 

Dr. Marie Gehle to perform a psychiatric evaluation of Campbell. Dr. Gehle

diagnosed Campbell with pedophilia but opined he was not at a high risk to reoffend. 

The State then obtained an independent evaluation from Dr. Ana Gomez. 

At the jury trial, Dr. Gomez testified on behalf of the State and was qualified

as an expert in psychiatry and forensic psychiatry. Dr. Gomez stated that after 

interviewing Campbell, conducting seven different psychiatric tests that accounted 

for various risk factors for reoffending, and examining the pertinent records in his 

file, she diagnosed him with pedophilic disorder, non-exclusive, indicating he was 

attracted to children of both sexes. She explained pedophilic disorder cannot be 

cured but can be managed through appropriate strategies and intervention. 

1 North Carolina v. Alford, 400 U.S. 25 (1970).
 

 

 

 

 

Dr. Gomez testified Campbell's proposed strategies to avoid reoffending—

including finding religion and "walking away" from children any time he was around 

them—were wholly unrealistic. Additionally, Dr. Gomez expressed concern over 

Campbell's refusal to seek sex offender treatment while incarcerated, which is in

itself a significant risk factor for reoffending. Dr. Gomez testified Campbell's

pedophilic disorder caused him serious difficulty in controlling his behavior, and his 

lewd act offense—committed while out on bond for the CSCM-1st offense—

indicated his difficulty in controlling his behavior was ongoing. 

As a result, Dr. Gomez opined Campbell was extremely likely to reoffend if 

he was not civilly committed. Further, Dr. Gomez testified the potential risk 

Campbell posed to future child victims was more imminent because, after his

release, Campbell planned to live with his sister, and her grandchildren and greatgrandchildren would frequently be sleeping in the same house as Campbell, as had 

his previous victims. In conclusion, Dr. Gomez testified it was her medical opinion 

Campbell met the criteria for designation as an SVP and he was in need of long-term 

control, care, and treatment at a secure facility. 

Dr. Gehle then testified on behalf of Campbell and was qualified as an expert 

in forensic psychiatry. Dr. Gehle stated that after performing a similar interview and 

review of Campbell's file, she had also diagnosed him with pedophilic disorder, nonexclusive type. Dr. Gehle explained that in coming to her diagnosis, she had used 

only one of the seven psychiatric tests performed by Dr. Gomez. However, on that 

test, both doctors scored Campbell in the low- to moderate-risk group for

reoffending, which equated to a rate of reoffending of 15.8% in the next five years

and 24.3% in the next ten years, approximately the average rate for reoffending for 

all sex offenders. 

Dr. Gehle testified that although she agreed with much of Dr. Gomez's 

testimony and diagnosis, she disagreed Campbell was likely to reoffend. Dr. Gehle

stated not every person convicted of a sex offense posed a high risk to the public 

upon his or her release, and Campbell's lack of prison referrals or disciplinary

problems showed his ability to control his behavior on a day-to-day basis. Dr. Gehle

also testified she was less concerned than Dr. Gomez about Campbell living with his 

sister and young children upon his release because it was unclear to her whether the 

children would actually spend the night or merely visit while other adult family 

members were present. Dr. Gehle then opined that, were Campbell to be released, 

there were safeguards in place to protect the public, such as placing him on the sex 

offender registry and monitoring him while on probation, including through the use 

of a GPS anklet. Ultimately, Dr. Gehle concluded that while Campbell suffered 

from a mental abnormality, there was insufficient evidence to believe Campbell's
 

 

 

 

 

 

abnormality made him likely to reoffend, and he therefore did not meet the criteria 

for designation as an SVP. 

On cross-examination, the State questioned Dr. Gehle's exclusive reliance on 

the results of the single psychiatric test, particularly when Dr. Gomez had testified

the test did not account for all of the risk factors associated with sexually 

reoffending, nor was the test intended by its creators as a stand-alone assessment. 

Furthermore, at the State's prompting, Dr. Gehle conceded Campbell had 

"meaningful risk factors" for reoffending, including a dysfunctional coping style, a

resistance to rules and supervision, and a refusal to receive mental health treatment 

unless it was court-ordered. Finally, Dr. Gehle testified Campbell did not have an 

"ideal relapse prevention plan" due to his failure to receive sex offender treatment 

and his post-release "access to children" who would sleep in the same house as 

Campbell, similar to his prior victims. However, Dr. Gehle stated she gave 

Campbell credit for claiming he would "walk away" from children and not be around 

them in "that way." 

On re-direct examination, Campbell attempted to rehabilitate Dr. Gehle's 

methodology for evaluating SVPs, emphasizing Dr. Gehle's vast experience in

evaluating SVPs and having her reiterate her opinion that Campbell was unlikely to 

reoffend. 

On re-cross examination, the State's attorney asked if Dr. Gehle had ever

wrongly opined an SVP candidate was unlikely to reoffend, to which Dr. Gehle 

responded she did not know. The State's questioning then focused on Dr. Gehle's 

pre-commitment evaluation of an unrelated sex offender, Michael Thomas. In doing 

so, the State's attorney handed Dr. Gehle her report on Thomas and requested Dr. 

Gehle read the portion of the report aloud where she had opined Thomas was

unlikely to reoffend and, therefore, should not be civilly committed as an SVP. The

State's attorney next handed Dr. Gehle an arrest warrant for Thomas dated 

approximately six months before Campbell's commitment proceeding and requested 

Dr. Gehle read portions of the arrest warrant into the record. The arrest warrant

stated Thomas was wanted for rape, and his DNA was a match for that of the alleged

rapist. The State emphasized Thomas had reoffended within two years of his 

evaluation by Dr. Gehle and the resultant failure to commit Thomas as an SVP,

stating that due to Dr. Gehle's error in opining Thomas should be released from 

custody, "another woman ha[d] been raped."

During closing arguments, the State's attorney concluded her remarks by 

reminding the jury that Dr. Gehle had been wrong before in opining other sex 

offenders were unlikely to reoffend, and that if Dr. Gomez was correct and Dr. Gehle 
 

 

was wrong again, Campbell was going to "get out and . . . hurt another kid." 

Hammering that point home, she stated:

So I leave you with this: You have a person who on more than one 

occasion [] has sexually assaulted children. He takes no accountability 

[for] what he's done and he hasn't had sex offender treatment and he's 

refused it when it has been offered. He's going to go live in a house

where people are going to allow him to be around children. You heard 

the testimony. What do you think is going to happen? 

At the conclusion of the hearing, the jury found beyond a reasonable doubt

that Campbell met the statutory definition of an SVP, and the trial court ordered 

Campbell's civil commitment. The court of appeals affirmed Campbell's 

commitment in an unpublished opinion.

II. Standard of Review 

In general, the admission or exclusion of evidence is a matter left to the sound 

discretion of the trial court, whose ruling will not be reversed on appeal absent an 

abuse of that discretion. Carson v. CSX Transp., Inc., 400 S.C. 221, 229, 734 S.E.2d 

148, 152 (2012). Likewise, the scope of cross-examination is largely within the trial 

court's discretion. Bunch v. Charleston & W.C. Ry. Co., 91 S.C. 139, 142, 74 S.E. 

363, 364 (1912). "An appellate court will not disturb a trial court's ruling concerning 

the scope of cross-examination of a witness to test his or her credibility, or to show 

possible bias or self-interest in testifying, absent a manifest abuse of discretion." 

Yoho v. Thompson, 345 S.C. 361, 365, 548 S.E.2d 584, 585 (2001).

"An abuse of discretion occurs when the trial court's ruling is based on an 

error of law or, when grounded in factual conclusions, is without evidentiary 

support." Clark v. Cantrell, 339 S.C. 369, 389, 529 S.E.2d 528, 539 (2000). "To 

warrant reversal based on the admission or exclusion of evidence, the appellant must 

prove both the error of the ruling and the resulting prejudice, i.e., that there is a

reasonable probability the jury's verdict was influenced by the challenged evidence 

or the lack thereof." State v. Commander, 396 S.C. 254, 263, 721 S.E.2d 413, 418 

(2011); State v. Colf, 337 S.C. 622, 625, 525 S.E.2d 246, 247–48 (2000) ("The scope 

of cross-examination is within the discretion of the trial judge, whose decision will 

not be reversed on appeal absent a showing of prejudice."). 
 

 

III. Discussion 

Campbell argues the court of appeals erred in affirming the trial court's 

decision to allow the State to cross-examine Dr. Gehle about Thomas's arrest warrant 

because the arrest warrant was irrelevant to the ultimate issue in the case, i.e., 

whether Campbell was an SVP. Campbell additionally contends the admission of 

testimony about Thomas's arrest warrant was more prejudicial than probative,

encouraging the jury to make its decision based on fear of Campbell rather than 

whether he met the statutory criteria to be declared an SVP. While we find the arrest 

warrant fell within the broad scope of relevant evidence, we agree that, under these 

facts, the arrest warrant was more prejudicial than probative. 

A. Relevance 

Relevant evidence is that evidence having any tendency to make the existence 

of any fact of consequence to the ultimate determination of the action more or less 

probable than it would otherwise be without the evidence. Rule 401, SCRE. 

Considerable latitude and discretion must be allowed the trial court in determining 

the relevance and admissibility of impeachment evidence. State v. Williams, 263

S.C. 290, 302, 210 S.E.2d 298, 304 (1974). As a result, "'anything having a 

legitimate tendency to throw light on the accuracy, truthfulness, and sincerity of a

witness may be shown and considered in determining the credit to be accorded his

testimony.'" State v. Jones, 343 S.C. 562, 570, 541 S.E.2d 813, 817 (2001) (citation 

omitted); see also Rule 611(b), SCRE ("A witness may be cross-examined on any 

matter relevant to any issue in the case, including credibility."). 

Here, Thomas's arrest warrant was a collateral matter because it could not

have been presented during the State's case-in-chief to prove Campbell was an SVP.

See State v. Bailey, 279 S.C. 437, 439–40, 308 S.E.2d 795, 797 (1983) (citations 

omitted) (holding evidence that the defendant's father and brother attempted to

procure perjured testimony was improperly admitted because it could not have been 

presented as part of the State's case-in-chief and, as a result, was collateral to the

defendant's guilt or innocence). However, given the "considerable latitude" with

which we must review the trial court's relevance determination, we find Thomas's

arrest warrant was in fact relevant to assist the jury in determining the weight to 

afford Dr. Gehle's testimony, and specifically her opinion as to whether Campbell 

was likely to reoffend. See, e.g., Rule 611(b), SCRE (stating a witness may be crossexamined as to any matter related to any relevant issue, including credibility); Jones, 

343 S.C. at 570, 541 S.E.2d at 817 (holding any evidence that shows the accuracy, 

truthfulness, or sincerity of a witness may be admissible to help the factfinder

determine the witness's credibility). As a result, the State was permitted to ask Dr. 
 

 

 

 

Gehle whether she was aware if she had ever erred in her SVP evaluations, and 

whether she was aware of a specific error.2

B. Unfair Prejudice 

Even when relevant, evidence may be inadmissible if its probative value is 

substantially outweighed by the danger of unfair prejudice. Rule 403, SCRE; State 

v. Wiles, 383 S.C. 151, 158, 679 S.E.2d 172, 176 (2009). "Evidence is unfairly 

prejudicial if it has an undue tendency to suggest a decision on an improper basis,

such as an emotional one." State v. Wilson, 345 S.C. 1, 7, 545 S.E.2d 827, 830 

(2001) (citing State v. Alexander, 303 S.C. 377, 382, 401 S.E.2d 146, 149 (1991)). 

The determination of prejudice must be based on the entire record and will generally 

turn on the facts of each case. State v. Stokes, 381 S.C. 390, 404, 673 S.E.2d 434, 

441 (2009). 

Prior to conviction, a defendant is presumed innocent in the eyes of the law. 

See State v. Posey, 269 S.C. 500, 503, 238 S.E.2d 176, 177 (1977) (declaring such a

statement "elementary"). Thus, a mere arrest warrant in no way proved Thomas in 

fact committed the offense for which he was arrested and, standing alone, could only 

have a minimal impact on Dr. Gehle's credibility. Accordingly, while it was relevant 

that Dr. Gehle may have opined in error that Thomas was unlikely to reoffend, 

Thomas's arrest warrant had very low probative value as to whether Campbell was 

an SVP. 

In contrast, the manner in which the State used the arrest warrant was highly 

prejudicial to Campbell. The State grossly mischaracterized the results of Dr.

Gehle's evaluations of Thomas and Campbell. As Drs. Gomez and Gehle both 

2 We note that had Dr. Gehle denied ever being wrong in her SVP evaluations, the 

State would have been bound by her answer and could not have introduced physical 

copies of Thomas's arrest warrant or called a witness to testify Thomas had 

subsequently been arrested for another sex offense. See State v. DuBose, 288 S.C. 

226, 231, 341 S.E.2d 785, 788 (1986) (per curiam) (holding where a witness denies

an act involving a matter collateral to a party's case-in-chief, the inquiring party is 

not permitted to introduce evidence in contradiction or impeachment). Similarly,

had Dr. Gehle denied ever being wrong, the State could not have skirted the rules

and indirectly introduced information from the arrest warrant by having Dr. Gehle 

read the warrant aloud because, of course, introducing testimony is the functional

equivalent of introducing evidence. Cf. State v. Starnes, 388 S.C. 590, 599, 698 

S.E.2d 604, 609 (2010) (stating testimony is evidence). 
 

 

 

 

 

 

 

testified, the results of the common psychological test they performed on Campbell

indicated he was in the low- to moderate-risk group. Individuals in that group have 

a rate of reoffending of 15.8% in the next five years and 24.3% in the next ten years, 

a rate which is consistent for that of all sex offenders. Therefore, by concluding 

neither Thomas nor Campbell met the statutory criteria to be classified as an SVP, 

Dr. Gehle did not guarantee either man would never reoffend. Rather, Dr. Gehle 

concluded the men were unlikely to reoffend. However, the State asserted otherwise

in its cross-examination and closing argument, stating that, based on an arrest 

warrant alone, Dr. Gehle had been "wrong" in her evaluation of Thomas; that as a

result, "another woman ha[d] been raped;" and that Campbell was likewise bound to 

"hurt another kid." 

Moreover, the State exacerbated the prejudicial effect of the arrest warrant 

during its closing argument. Specifically, the State emphasized that on multiple 

occasions, Campbell had assaulted children sleeping in the same house as him, 

refused to accept responsibility for his actions, declined to receive sex offender

treatment while imprisoned, and was planning to live in a house in which minor 

children would regularly sleep. The State's attorney then asserted, "You heard the 

testimony. What do you think is going to happen?"3 This rhetorical question—the

last statement the jury heard prior to its deliberations—was a naked attempt by the 

State to appeal to the jurors' emotions and cloud their ability to impartially weigh

the evidence. See Tappeiner v. State, 416 S.C. 239, 254 n.8, 785 S.E.2d 471, 478 

n.8 (2016) (finding an emotional plea to jurors that an accused rapist was a bad actor

and could not be trusted to watch the jurors' own family members had a strong 

prejudicial impact on jurors' impartiality in part because "the emotional plea was the 

very last thing the jury heard before beginning its deliberations . . . [and therefore]

was likely at the forefront of the jurors' minds when beginning their discussions"); 

Von Dohlen v. State, 360 S.C. 598, 609, 602 S.E.2d 738, 744 (2004) (holding the 

State must tailor its closing arguments so as not to appeal to the personal biases of 

the jury or arouse the jurors' passions or prejudices). 

Weighing the minimal probative value of Thomas's arrest warrant against the

prejudice resulting from the State's mischaracterization of the import of the warrant, 

we hold the admission of the warrant unfairly prejudiced Campbell because it had

3

 Generally, this statement is not problematic. However, in the context of this case,

this innocuous statement magnified the unfair prejudice caused by the State's

improper use of Thompson's arrest warrant to attack the credibility of Campbell's

expert witness. 
an undue tendency to suggest a decision on an improper basis, namely fear he would 

reoffend and harm another child. See Wilson, 345 S.C. at 7, 545 S.E.2d at 830 (citing 

Alexander, 303 S.C. at 382, 401 S.E.2d at 149) (stating evidence is unduly 

prejudicial if it suggests a decision on an emotional basis, rather than a factual one). 

Additionally, we find the error was not harmless because the case against Campbell 

amounted to a "battle of the experts," in which Dr. Gomez opined Campbell 

presented an imminent danger to the community, and Dr. Gehle opined Campbell

was unlikely to reoffend. As such, we find the improper denigration of Dr. Gehle's

credibility was reasonably likely to have affected the outcome of the trial. Cf. 

Tappeiner, 416 S.C. at 253–54, 785 S.E.2d at 478–79 (finding the State's improper 

vouching for the victim's credibility and its emotional appeal that the defendant was 

a bad actor who could not be trusted to watch the jurors' own family members was 

not harmless error because the case was "entirely dependent on a credibility 

determination between the prosecution's witnesses and the defense's witness," and 

therefore, it was "likely the emotional plea, particularly in conjunction with the 

solicitor's improper vouching for Victim's credibility, swayed the jurors' view of the 

facts and resolution of the contradictions in the witnesses' testimonies"). 

IV. Conclusion 

The decision of the court of appeals upholding Campbell's SVP status and his 

involuntary commitment is reversed and remanded for a new commitment 

proceeding. 

REVERSED AND REMANDED.
