Court testimony: Father testifies of struggle with son-in-law

Prosecutors honed in on Thomas Martens’ FBI training, trying to poke holes in his version of events that led to Jason Corbett’s death in the early morning hours of August 2, 2015.

Martens, a 31-year veteran of the FBI who had high-level security clearance, claimed he hit Jason Corbett on the head with a baseball bat in self defence.

“I hit him until he goes down and then I step away,” Martens testified on direct examination.
