The trial got underway Monday for the man accused of shooting and killing a karaoke disc jockey at a south Nashville bar three years ago.
Investigators say Hank Wise shot and killed Ben Goeser at Jonny's Sports Bar in front of a crowd of people on the night of April 2, 2009.
Detectives said Wise had developed a fascination with Goeser's wife and had sent her inappropriate messages on MySpace.
“He sent me that message and I showed the message to my husband and I was like, ‘Ben read that,' and he was like, ‘What in the world?' and I was like, ‘Yeah, I don't know what to think about that,' and he said, ‘Yeah he has a crush on you,'” Nikki Goeser testified.
Wise is accused of opening fire after Nikki Goeser told the bar manager that Wise's presence made her uncomfortable, prompting the manager to ask Wise to leave.
Metro police said around 50 patrons were inside the bar at the time, three of whom quickly jumped Wise, disarmed him and held him until police arrived.
Goeser, 49, died at the scene.
Wise's trial is a bench trial meaning there is no jury.
The defense says Wise client suffers from a severe mental illness called delusion disorder.
The trial resumes on Tuesday when the defense is expected to call a mental health specialist as their next witness.
