It is day two for the man accused of killing his roommate.

Leo Dorbad faces first degree murder charges after prosecutors say he shot 28 year old Dawn Luciano in the head.

The trial began with opening statements from the prosecution and defense. The jury heard testimonies from Luciano's family and friends Tuesday. Witnesses say Luciano had actually mentioned being afraid of Dorbad. Dorbad admits he shot Luciano, but he says it was an accident.

Deputies say Dorbad's story seemed to change during the interview process and eventually was charged with first degree murder.

"There are a lot of different things that help tell the story," says Spencer Mann, State Attorney's Office. "And thats's why we believe we can prove without a reasonable doubt that the defendant committed the crime.

The State Attorney's Office says with first degree murder charges, Leo Dorbad could face up to life in prison if convicted. The case did not meet the threshold for the death penalty. The trial is expected to last the rest of the week.
