WARREN, Ohio - After two years in jail, a Warren man went on trial Friday for murdering his parents in 2011.

Dressed in street clothes, 33-year old Louis Mann was escorted to court for the start of the trail that will determine his fate. Mann is accused of murdering his parents Fran and Philip Mann at their Jefferson Street home in Warren. In court, Mann listened as investigators testified about what they found at the crime scene, and how the coroner's report said that Mann's father was beaten and shot in the head and his mother was strangled with a clothesline.

The day after the victim's were discovered in the home, the fathers car was located at a motel in Howland and that's where Mann was taken into custody. He was taken to police headquarters for questioning. The interrogation was videotaped and that video was played on a large screen in the court room.

Detectives say the tape shows Mann breaking down in tears and confessing to the murders.

On tape, Mann talks about just being released from jail on other charges, and arguing with his mother about custody of his children. At one point he says "I just lost it, I snapped". During the playing of the video Mann only took brief glances at the screen.

Mann's lawyers have indicated they do not plan to call any witnesses, but if the verdict is guilty they will present arguments in mitigation to spare Mann from a death sentence. The trial, before a jury of eight men and four women will resume next week.
