The Mt. Hebron M.E. Church South and Cemetery is a historic Methodist church at 1079 Mt. Hebron Road in Colville, Arkansas.
 The church is a modest Plain Traditional wood frame church, built in 1904 for a congregation established in 1872.

Debra Jean Milke (née Sadeik; born March 10, 1964) is a German-American woman who spent over 25 years in prison in the state of Arizona.
 She was one of three people sentenced to death for the December 2, 1989 shooting death of her four-year-old son, Christopher Conan Milke.
 Her alleged conspirators were her roommate James Lynn Styers and his friend Roger Mark Scott.
 Neither testifed against her and both agreed that she was not present at the shooting.
 Scott implicated Milke as the mastermind while Styers said she had no involvement whatsoever.
 They implicated each other as the actual shooter.
 Who that was remains a subject of speculation.
In the Hour of Chaos is a 2016 American documentary film directed by Bayer Mack.
 It details the life and various trials of the Reverend Martin Luther King Sr. ("Daddy King"), including his violent, poverty-stricken upbringing in rural Georgia, the assassination of his oldest son (civil rights leader Martin Luther King Jr.), the drowning of his younger son Alfred Daniel Williams King and the shooting death of his wife, Alberta Williams King.
A rare functional variant is a genetic variant which alters gene function, and which occurs at low frequency in a population.
 Rare variants may play a significant role in complex disease, as well as some Mendelian conditions.
 Rare variants may be responsible for a portion of the missing heritability of complex diseases.
 The theoretical case for a significant role of rare variants is that alleles that strongly predispose an individual to disease will be kept at low frequencies in populations by purifying selection.
 Rare variants are increasingly being studied, as a consequence of exome and whole genome sequencing efforts.
 While these variants are individually infrequent in populations, there are many in human populations, and they can be unique to specific populations.
 They more likely to be deleterious than common variants, as a result of rapid population growth and weak purifying selection.
 They have been suspected of acting independently or along with common variants to cause disease states.
The shooting of Antonio Martin occurred on December 23, 2014, in Berkeley, Missouri, a suburb of St. Louis.
 Martin, an 18-year-old black male, was fatally shot by a white Berkeley police officer when Martin pulled a gun on him.
 The shooting sparked protests in the St. Louis area and other cities in the U.S.
 The shooting elicited comparison to the earlier shooting death of Michael Brown two miles away in Ferguson, Missouri.

 Butler subsequently confessed to the crime, and the case went to trial.
 However, during the trial he testified that he had been brutalized into his confession, and he was acquitted.
 The case gained significant notice in the media, and became the subject of an award-winning documentary, "Murder on a Sunday Morning".
