UPDATE: County Police Chief Arrives on Crime Scene

Update 2 p.m.: St. Louis County Police Chief Tim Fitch has arrived on the scene. Police are beginning to bring bodies out of the home.

St. Louis County police say they found several bodies inside a home in the 5300 block of Vine Avenue.

Ron Monks, who lives across the street on Mathilda, said he heard what he thought were three gunshots around 10 a.m.

"I heard three loud pops, and I thought they were fireworks with the Memorial Day holiday and all," he said. "Then the police arrived."

Webb Bennett, from the 5300 block of Vine, said his daughter went to school with a teen who lived in the house.

"She was supposed to graduate from Affton High School tonight," he said.

Interim Affton school superintendent Ken Weissflug said he couldn't comment on the residents of the home because of the ongoing investigation. He said graduation was scheduled at 7 p.m. at Affton High and that is was too soon to say whether any changes would need to be made in that schedule.

"We always have plans in place; at this point, we just don't know," he said.

Yvonne Terry, who also lives on Mathilda, said the family who lived in the house was quiet.

"This is a first for this neighborhood," she said. "Nothing ever goes down here."

The home at 5352 Vine in Affton is owned by Dianna L. Dreiman, according to St. Louis County property records.
