On April 12, 2005, Charles Edward Parker Sr., 54, and his wife Diane, 54, were found shot to death in their Conway, South Carolina, home. Their son, who worked with his father at the family mirror and glass business on the property, discovered the couple.

Investigators initially focused on Richard Gagnon, the daughter’s boyfriend. Prosecutors presented circumstantial evidence that included a spot of Charles Parker Sr.’s blood on Gagnon’s shoe and informant testimony; Gagnon was convicted in 2007 and sentenced to life in prison. A small drop of blood from the crime scene did not match Gagnon’s DNA and was later uploaded to a national database. That profile led to Bruce Antwain Hill, whose DNA had been collected after a Tennessee robbery.

Hill was tried and convicted in 2011 for the murders and sentenced to life without parole. The discovery tying Hill to the scene ultimately resulted in Gagnon being granted a new trial; the charges against him were dismissed and he was exonerated in 2015. Does anyone have information about the Parker family, their business, or the days around April 12, 2005?
