On February 17, 1998, the body of Maryette Griffin, a drug-addict and prostitute, was found partially clothed amidst a pile of garbage in a garage on North 7th Street in Milwaukee, Wisconsin. She had been strangled.
In March, William Avery, 25, who ran a nearby crack house, learned that police wanted to talk to him, and voluntarily went to police. Police contended that he acknowledged that he had been seen with her in the hours preceding her death and that he had been “grabbing” her, but couldn’t remember anything else because he blacked out. Avery later contended this was a fabricated statement.
With little other evidence linking him to the murder, police did not charge him with the murder. However, they did charge him with drug-dealing. Avery was convicted in 1998 on the narcotics charges and sentenced to 10 years in prison.
In 2004, Milwaukee County authorities charged Avery with reckless homicide in the death of Griffin after three prison inmates contended he had confessed to killing her. One of the inmates recanted prior to trial and did not testify. The other two testified that Avery admitted to the murder.
Avery was convicted on March 9, 2005 and sentenced to 40 years in prison.
In April, 2010, Avery wrote to the Milwaukee County District Attorney’s office, requesting that DNA tests be performed on a sample taken from Griffin’s mouth. The DNA tests excluded Avery and matched the profile of Walter E. Ellis, an accused serial killer.
Ellis had been charged in September 2009 with killing seven prostitutes in Milwaukee over a 21-year period. He was linked to all seven murders by DNA tests.
Avery was released from prison in May, 2010 and on September 23, 2010, his conviction and sentence were vacated and the charges were dismissed.
In February, 2011, Ellis pled no contest to the murders of seven prostitutes and was sentenced to life in prison without parole. No one was charged with the murder of Griffin. Ellis, who died in prison in 2013, was also linked to a murder for which Chaunte Ott
was wrongly convicted and ultimated exonerated.
In April 2011, Avery filed a wrongful conviction lawsuit in U.S. District Court in Milwaukee. During the civil lawsuit, both of the inmates who testified at trial recanted their trial testimony.
The Wisconsin Claims Board awarded Avery $25,000 in compensation in December 2012. In June 2015, a jury hearing hte federal suit awarded Avery $1 million in damages.
