Janitor convicted in co-worker’s slaying seeks new trial

BURLINGTON, Ky. (AP) – A janitor serving life behind bars for the murder of his co-worker at a biotech company is hoping for a retrial because of new evidence.

David Dooley has maintained his innocence in Michelle Mockbee’s death. The 42-year-old was found beaten to death outside her office at Thermo Fisher Scientific in Florence, Kentucky in 2012.

Dooley’s attorneys have said there was no physical evidence linking him to the slaying. They’re seeking a new trial, saying the prosecutor and lead detective withheld a surveillance video showing someone trying to enter a building hours before Mockbee’s death.

News outlets report Dooley’s former attorneys testified Tuesday that they’d never seen the footage, and if they had, it may have changed the outcome.

Prosecutor Tally Smith’s attorney says she gave the defense all the evidence.
