A car similar to Bowens’ was also caught on camera, and a security guard identified Bowens in court as the person she saw enter and leave the hotel at the time of the murder.

Prosecutors said Knopfel’s DNA was found on a leather jacket found at Bowens’ home — a jacket that matched the one the robber was seen wearing. Also, they said, an autopsy revealed Bowens’ DNA on Knopfel’s left hand.

Cell tower data also put Bowens near the scene that night, prosecutors said.

Bowens’ attorney, Celestine Dotson, had argued the DNA evidence was flawed and that her client had been mistakenly identified as the robber.

Bowens’ first-degree murder conviction will mean an automatic sentence of life without parole. The St. Louis jury, which deliberated only a couple hours after a three-day trial, also found him guilty of first-degree robbery and two counts of armed criminal action.
