A man has been arrested nearly 16 years after a Georgia mother-of-four was stabbed to death while working at a cell phone shop.

Willie James Jr, 58, of Wayne County, was arrested and charged with malice murder, felony murder and aggravated assault in the death of Sandra Robinson, according to the Georgia Bureau of Investigation.

Robinson was 32 years old when she was killed on March 17, 2010, while working at the Prepaid Superstore on South Madison Avenue in Douglas, a small city about 120 miles south of Savannah.

Investigators said the attack happened between 6pm and 7pm, while the business was open.

Police say Robinson was stabbed inside the store, which sits near several other businesses including a Walgreens, a probation office and Rountree Park.

The killing shocked the local community and left Robinson’s four children without their mother.

Authorities said the suspect was someone who knew Robinson and had been seen frequently at the store prior to the attack.

The case remained unsolved for years until new forensic testing linked James to the crime scene, the Georgia Bureau of Investigation said in a press release, though officials have not disclosed the specific evidence.

James was taken into custody on March 2 and is now being held in the Coffee County Jail.

The Georgia Bureau of Investigation said the arrest was the result of years of collaboration between multiple agencies and forensic specialists working to reexamine evidence from the case.

For Robinson’s family, the arrest represents a long-awaited step toward accountability.

Her son Trey Robinson, who was 17 when his mother was killed, said his family believes the case is finally moving toward justice after years of uncertainty.

‘I feel without a shadow of a doubt we’re going to get justice for my mom. 

‘He’s going to have to suffer the consequences of his actions. So I’m going in feeling good,’ he told WALB. 

Remember his mother he said that she ‘was a comedian’ and ‘liked to have a good time.

‘So when I think about my mom, it’s always the smallest things that, you know, they get me a little emotional.

‘But now, all we have left are memories. So we’re going to dwell on those memories and the good times that we had.’

For years, the case remained listed on the GBI’s unsolved homicide database, where authorities offered a $1,000 reward for information that could help identify the killer.

Authorities said the case remains under investigation.
