Police named a new person of interest on Monday in the unsolved 2007 slaying of a North Richland Hills woman who was shot after she answered a knock at her front door.
Marianne Wilkinson, 68, was shot multiple times in an apparent case of mistaken identity, police said.
The person of interest is Willie Boley, 36. Public records show he has lived in Palestine, Tennessee Colony and Fort Worth.
North Richland Hills police Sgt. Keith Bauman would not explain why Boley has come under scrutiny. NBC DFW could not reach Boley for comment.
He has not been charged in connection with the murder.
Boley has a criminal record, including a charge he beat his wife in August 2012.
According to the Palestine Herald, Boley broke her nose and dragged her during a late-night argument. She also sustained two black eyes and bruises.
The latest news from around North Texas.
Investigators have theorized from the beginning that Wilkinson was killed by mistake.
Police had previously named a neighbor as a person of interest in the case. The man lived exactly one block over from the Wilkinson’s and had the same house number. He was undergoing a nasty divorce, according to previous news reports.
Investigators recovered the gun believed used in the crime but do not know the identity of the shooter.
Wilkinson's son Mike credited police with never giving up on the case.
"The fact they've been as persistent as they have has been a huge blessing and help to us, to believe that whoever is responsible will be caught," he said.
A $10,000 reward for information in the case is being offered by Oak Farms Dairy, police said.
