MUSKEGON, MI - A 55-year-old mother of a rape suspect is accused of threatening one of her son's alleged victims. 
 
 Lynette Sue Humphrey, the mother of Joshua Matthew-Rolling Humphrey, allegedly threatened in a voice mail message to "beat up" one of her son's alleged victims. Joshua Humphrey, along with Larry Donell Stiff, has been charged in the "date-rape drug"-related rapes of two women in the Muskegon area. 
 
 Lynette Humphrey, of 613 Taffy Lane, was charged last week with witness intimidation as a third-time habitual offender and is lodged in the Muskegon County Jail on a $20,000 bond. She faces up to 20 years in prison. 
 
 Joshua Humphrey, 34, and Stiff, 31, have been charged with third degree criminal sexual conduct involving a Feb. 7, 2016 incident with one woman, and as first-degree criminal sexual conduct accomplices in an incident involving another woman in 2013. They were charged in March for the 2016 case, and on July 8 for the 2013 case.

 'I couldn't move,' woman testifies against suspect in two drugged rape cases ||||| MUSKEGON, MI -- Two women testified in court to losing consciousness and part of their memory after accepting a drink from men they had just met, later waking up naked and sore on a bed in a Muskegon basement. 
 
 Larry Donell Stiff, 31, appeared on Tuesday, July 26, for a 60th District Court preliminary hearing on charges of first-degree criminal sexual conduct accomplices. Stiff and Joshua Matthew-Rolling Humphrey, 34, were charged on July 8 for an incident in 2013. 
 
 The men are charged in the "date-rape drug"-related rapes of two women in the Muskegon area and prosecutors believe there may be many more victims. In March, Stiff and Humphrey were also charged with third degree criminal sexual conduct involving a Feb. 7, 2016 incident with another woman. 
 
 Senior Assistant Prosecutor Robert F. Hedges called his first witness, a 24-year-old Grand Rapids woman referred in search warrant affidavits as "Woman A," who said she met Humprey on a dating website. After communicating on the Internet and texting for a few weeks, they agreed to meet in person for dinner in Muskegon. 
 
 The woman said she drove alone to Humphrey's home at 1143 Oaklea St. on Oct. 30, 2013. She was nervous, and said she spoke to him while inside her car for a few minutes. 
 
 Humphrey changed their plans, and the woman agreed to drive in his "crappy Ford pickup truck" to the now-closed Cancun Connections bar at 2411 Hall Road. On their way there, she testified that Humphrey stopped at an apartment while she waited in the car. 
 
 The woman said she left her car at Humphrey's home. 
 
 At the bar, the woman said they met Stiff, who she recognized from the same Internet dating website, and another woman. The second woman was referred to in police records as "Woman B." 
 
 The two women learned they shared mutual friends and spent the majority of their time at the bar together with Stiff and Humphrey. Neither had met the men before. 
 
 "I was concerned that something bad was going to happen," the first woman said. She texted her best friend, an older sister and a boyfriend while the two women stepped outside for a cigarette. 
 
 When they returned to the bar, Humphrey offered them a shot of clear liquor, which the women accepted. Both testified that he walked up with each drink in hand and did not see him order them from a bartender. 
 
 Before that point, Woman A said she had consumed less than one beer, but within 15 to 20 minutes began to feel strange. The second woman testified consuming marijuana and "one or two beers and two shots" that night. Both testified the strange feeling they had was not from alcohol. 
 
 "I went to the bathroom and felt kind of tired, drowsy and out of it," she said. "My friend tried to get ahold of me. I answered the phone and didn't know where I was. I said I would call her back and that's where I lost everything. I don't remember much of anything after that." 
 
 The woman remembers asking Humphrey to leave the bar and then entering a stranger's house with Stiff and the other woman. 
 
 "We went downstairs from the garage of a home into the basement," she said. "I remember cement walls and it was very dirty. We went to a room on the right; inside was a bed on the floor and a couch." 
 
 She said she remembers sitting on the couch with Humphrey and the other woman before she passed out. Her first clear memory was of waking up the next day, lying naked next to Woman B, who was also naked and asleep on the bed. 
 
 The second woman remembers a bit more. 
 
 "I couldn't really move off the couch," she said while choking back tears. "Then I remember lying on the bed not being able to move. I blacked out again then there was man on top of me." 
 
 "I couldn't move," she said, adding that he could feel he had penetrated her. 
 
 Neither testified to giving Still or Humphrey permission for sex. The first woman said she and Humphrey had already agreed to meet as friends only. 
 
 "I was sore, that's when I knew something had happened," she said. "I told (Woman B) I needed to get her out of there; she was freaking out and pretty out of it. I was too, but I knew what I needed to do to get out of there safely in the most calm way possible." 
 
 The second woman testified that she had an argument with Stiff about the location of her cell phone, then left on foot and in the rain at 4 a.m. Meanwhile, Humphrey drove the first woman back to her car and she left, still without her phone, to her sister's home, arriving 6 a.m. the next day. 
 
 The first woman called the Wyoming Police Department that morning, who referred her to Muskegon police. She had a rape test and was later contacted by Muskegon Police Department Detective Steve Irvine. 
 
 State police crime lab rape test swab reports found DNA that matches Stiff, evidence showed. A toxicology report also found Amitriptyline in the woman's system, an odorless, soluble compound used as a prescription antidepressant. 
 
 The second woman did not report the incident to police but was contacted by Muskegon detectives less than a week later. She was able to point out the home where they spent the night, but could not remember the address in court. 
 
 Kostrzewa granted Hedges' request to adjourn Stiff's preliminary examination until 11 a.m. on Aug. 9, to allow both detectives in charge of the investigation to return from vacation. 
 
 Hedges said he will likely ask the court add an additional count of first-degree criminal sexual conduct for the second woman. Both Stiff, who was represented by Public Defender Adam Masserang, and Humphrey are charged as second time habitual offenders and face a potential life felony with first-degree criminal sexual conduct. 
 
 Muskegon police ask anyone with information about Joshua Humphrey and Larry Stiff or who believes they have been a victim is asked to call the detectives at (231) 724-6750 or Silent Observer, (231) 72-CRIME. ||||| MUSKEGON, MI - Two men have been charged in the "date-rape drug"-related rapes of two women in the Muskegon area and prosecutors believe there may be many more victims. 
 
 Joshua Matthew-Rolling Humphrey, 34, and Larry Donell Stiff, 31, have been charged with third degree criminal sexual conduct involving a Feb. 7, 2016 incident with one woman, and as first-degree criminal sexual conduct accomplices in an incident involving another woman in 2013. They were charged in March for the 2016 case, and on July 8 for the 2013 case. 
 
 In the 2013 case, there is possibly another female victim, and charges may come for that, Muskegon County Chief Assistant Prosecutor Timothy Maat said. 
 
 The men drugged the women before raping them, Maat said. The prosecutor's office is reviewing other cases involving "at least a dozen victims," he said. 
 
 Maat urged other possible victims to step forward and for the public's help in obtaining additional information against Humphrey and Stiff. 
 
 Sworn search warrant affidavits indicate that Humphrey told police he has herpes. 
 
 A search warrant was obtained for Humphrey's medical records after police learned that Humphrey had been prescribed Tramadol HCL. 
 
 Police say it had been refilled 22 times in six months, between July 2015 and January 2016. Tramadol is restricted to five refills in six months because it is a Schedule IV controlled substance. 
 
 Police said the effects of Tramadol are very similar to those described by the alleged rape victims. Tramadol is an addictive narcotic pain reliever that can cause nausea, dizziness and drowsiness, especially when taken with alcohol, according to the Mayo Clinic's web site.

 Messages were left seeking comment from Humphrey's and Stiff's attorneys. 
 
 Here are details, culled from search warrant affidavits, of the cases Stiff and Humphrey are accused of: 
 
 Oct. 31, 2013: A woman referred to here as "Woman A" told police she met Humphrey on an Internet dating web site and after communicating a couple weeks they decided to meet in person. She went to his home at 1143 Oaklea St. and he drove them to the now-closed Cancun Connections bar at 2411 Hall Road. 
 
 There they met up with Stiff and a woman referred to here as "Woman B." At one point, the men give the women shots of a dark liquid. The group left and ended up at Stiff's house. Woman A told police on Nov. 4 she last remembered sitting on a couch before she passed out, later waking up naked and lying next to Woman B whose pants and underwear had been pulled down. Woman A goes to the hospital and a rape test is performed, later turning up DNA of two men, one of them Stiff's. Police received a search warrant to do DNA testing on Humphrey. 
 
 Woman B tells police that "everything began to blur" when they left the bar and that she too remembered sitting on a couch and then blacked out, though she groggily came to a couple times and noticed a man was on top of her and the other was on top of Woman A. She also sensed being sexually penetrated. "She could not move or talk," the detective swore in the affidavit. 
 
 A few weeks later, Woman A tells police that Humphrey was sending her text messages, including one warning her about making a false police report, that she should be careful of committing slander and that "everything u did that night is on camera so whatever u are trying to pull won't stand." 
 
 The Muskegon County Prosecutor's Office received on July 8, 2016 from the Muskegon Police Department the complaint seeking criminal sexual conduct charges in the 2013 incident. Both Stiff and Humphrey were charged that same day with first degree CSC, a potential life felony. Both are charged as second time habitual offenders. Maat said another CSC charge could be added for the assault on Woman B. 
 
 Muskegon Police Chief Jeffrey Lewis declined to comment on the case, including why it took police nearly 3 years to bring the 2013 complaint to the prosecutor's office. 
 
 "This is an open case proceeding through the judicial system," Lewis said. "It would be inappropriate to comment at this time." 
 
 Feb. 6, 2016: "Woman C" meets up with Humphrey, whom she knows, and another man she doesn't know at the Marine Tap Room, 1983 Lakeshore Dr. Woman C brings two friends with her because she had heard negative things about Humphrey, including that he was "rapey" and "creepy," according to court documents.

 She ate pizza and drank beer with her friends and Humphrey bought her one beer. She didn't remember anything after that until she woke up in her own home wearing surgical scrub pants, no underwear and her bra and top askew. She said she didn't own scrubs and had never before seen the ones she woke up wearing. 
 
 One of Woman C's friends told police Woman C met Humphrey on the Tinder dating web site and he later tracked her down on Facebook. 
 
 The prosecutor's office on March 18 filed third degree criminal sexual conduct charges against Humphrey and Stiff in the assault of Woman C. That charge is punishable by up to 15 years in prison. 
 
 In another case in which charges have not been brought, "Woman D" told police she met Humphrey on Facebook and agreed to see him in person at "Mike (cq) Bar," according to a court affidavit. There Humphrey told her about a local guy putting the date rape drug in women's drinks and how easy it was to make with common household items. 
 
 On a later night, Woman D met up with Humphrey and his friend "Larry" at 22 Below, 22 S. Harbor Dr. in Grand Haven, according to the affidavit. Humphrey kept asking to smell her drink and within minutes of taking a drink she "began to feel very sedated," the detective swore on the affidavit. She called a friend to take her home and needed help walking. Woman D had no memory for part of the night and later learned that Humphrey had come to her house but was told by others to leave. The next day she was very sick and vomiting and felt that she had been drugged, according to the court document. 
 
 Woman D was interviewed in March 2016, but it is not clear when the incident occurred. 
 
 Muskegon police ask anyone with information about Joshua Humphrey and Larry Stiff or who believes they have been a victim is asked to call the detectives at (231) 724-6750 or Silent Observer, (231) 72-CRIME.
– Joshua Humphrey faces life in prison for allegedly drugging and date-raping two women; his 55-year-old mother's alleged response could earn her up to 20 years in prison as well. MLive reports Lynette Sue Humphrey was last week charged with witness intimidation as a third-time habitual offender. The Muskegon, Mich., woman allegedly called one of the two women at the heart of her son's case and left her an intimidating voicemail about beating her up. Muskegon County Chief Assistant Prosecutor Timothy Maat has accused Joshua Humphrey, 34, and Larry Donell Stiff, 31, of drugging and then raping two women, one in 2013 and one in February 2016. "At least a dozen" women's cases are being reviewed to see if there's a connection, reports MLive. MLive reports "Woman A" and "Woman B" testified in court this week about their Oct. 30, 2013, encounter with Humphrey and Stiff. Woman A, a 24-year-old Grand Rapids woman, said that after meeting Humphrey online, the two went to a bar and met Stiff and Woman B there. Both women testified that they accepted a clear shot from Humphreys and felt strange soon after, though Woman A hadn't yet finished a full beer. They ended up at a home, and Woman B said, "I remember lying on the bed not being able to move. I blacked out again then there was man on top of me." Woman A's rape test returned Stiff's DNA and the prescription drug Amitriptyline. Woman B was contacted by police a week later; prosecutors want charges brought in connection with her alleged rape. The 2016 case involves "Woman C." It's unclear which woman Lynette Humphrey allegedly called.
