BLACK JACK, Mo. – A 69-year-old Black Jack man is in jail Monday evening for allegedly strangling his sister during an altercation in his home.

According to Sgt. Tracy Panus, a spokeswoman for the St. Louis County Police Department, officers responded to a call regarding an assault just after 8 p.m. Sunday at a residence in the 11900 block of Barden Tower Road.

Police identified the woman as 67-year-old Silvia Freeman. She was stabbed and strangled by her brother, 69-year-old John Freeman.

A neighbor who didn’t wish to be identified said she’s trying to wrap her head about what happened to the woman she’d seen all the time, jogging along her street.

“She’s a nice, she was real quiet, kept to herself, she’d tend to her yard,” she said.

The elder Freeman greeted the first officer to arrive at his door. Police claim he had “a significant amount of blood” on him.

Freeman allegedly told the officer that he’d killed his sister, Panus said. The officer went inside and found the body of Silvia Freeman on the floor. She’d been stabbed in the neck multiple times and was pronounced dead at the scene. She was 67.

A broken glass vase covered in blood was located near the victim’s body.

John Freeman was taken into custody.

Silvia’s neighbor described seeing her jogging that same day at 2 p.m.

“And I was just thinking she’s doing her normal thing, and she was right about here, and she turned around, and she looked back at me,” she said. “It’s kind of hard for me to move past it. Only to find out what, about six hours later, she’s murdered.”

The St. Louis County Prosecuting Attorney’s Office charged John Freeman with second-degree murder and armed criminal action. He remains jailed on a $500,000 cash-only bond.
