Day 3 of testimony in David Dooley murder retrial

Testimony continues Friday in the murder retrial of David Dooley, who is accused of killing his coworker in 2012. Dooley is accused of killing Michelle Mockbee at Thermo Fisher in Boone County. He was convicted in 2014, but a judge granted him a retrial because his defense attorneys said they never saw video showing a man near the building hours before Mockbee was killed.
