A teenager in Mississippi knew the elderly couple he's accused of killing before sparking a standoff with law enforcement, according to new testimony in court.

Cordarius Hobbs, 17, is charged with killing 74-year-old Billy Blair and his 71-year-old wife Virginia Carol Blair during a home break-in on June 3 in Mendenhall, Mississippi. Family members of Hobbs testified during the Thursday preliminary hearing that he knew the couple.

Family members testified that Hobbs did work for the Blairs for things like cleaning around the house before the alleged shooting, according to Mississippi Bureau of Investigation investigator.

By noon, the investigator said that officers arrived and were met with shots fired at them, starting a nearly two-hour-long standoff. Hobbs was captured after trying to run away from officers, the official said, adding that the teen was unarmed when he was caught.

Carol Blair was found in a bedroom curled in the fetal position and had three gunshots to the back of her head. Bill Blair was found lying on his back in the kitchen with three gunshot wounds to his face.

The state investigator said three firearms were found inside the home as well as 280 shell casings, all owned by Bill Blair.

Hobbs' defense attorney, Zachary Vaugh, argued that there's a lack of direct forensic evidence connecting the teenager to the shooting.

"There was nothing to say he’s a principal, he’s the one that pulled the trigger on these things," Vaugh said. "One of the things alone was, one of the victims was shot twice on one side of the head and once on the other. I think that’s pretty compelling that somebody else may have been in there. There’s a lot of things that are possible, just a tremendous amount of things."

"When you have an officer say there’s no one that can identify him at the time of the shooting, I just don’t see how that adds up," he said.

Hobbs is charged with two counts of capital murder and one count of burglary, in addition to 10 other charges. He was denied bond.

In a statement on Facebook, the couple's family previously said, "We are crushed in spirit, bruised, and brokenhearted, but we are not alone."

Jason Busby, who was friends with the couple, remembered them as being extremely selfless when speaking with WLBT.

"The man would’ve given you the shirt off his back, his wife is the same, and they’re just great people. It’s just a tragedy," Busby said. "Everybody around here is still in shock. They were just good people."
