DES MOINES, Iowa -- The jury was handed the case in the trial of a Pleasant Hill man.
David Moffitt, 27, is charged with first degree murder in the death of his ex-girlfriend's fiancé Justin Michael, 30. Police say Moffitt broke into Michael's Grimes home in May of 2014 and shot him to death while he was sleeping next to his fiancé.
Moffitt is pleading not guilty by reason of insanity.
Late this afternoon the prosecution and defense gave closing arguments to the jury. Prosecuting attorney Steve Foritano says Moffitt deliberately targeted Justin Michael and killed him after he found out Michael was engaged to his ex-girlfriend.
"On May 8, 2014 he knew exactly what he was doing, he knew exactly the consequences. Anger, jealousy, revenge, those are all motives for murder."
Fortiano says the evidence proves Moffitt knew what he was doing when he pulled the trigger. He says Moffitt researched homicide, bought a gun, conducted target practice, and tried to frame the crime on someone else.
"He had a plan and the purpose of planning a murder, so he did the research, the research to try and get away with murder."
Moffitt's defense attorney, Kevin Rigg, told the jury his client clearly wasn't in the right state of mind at the time of the crime.
Rigg says Moffitt had a psychotic break when he found out about the engagement and didn't know the difference between right and wrong at the time of the murder.
"That's how you take someone who in 13 months had no problems at all and all of a sudden it's a good idea to take an assault riffle and put it 12 inches from someones head and pull the trigger 4 times, because it doesn't make sense unless all the rational has left him."
A psychiatrist, who testified on behalf of the defense, said Moffitt was on a combination of medications that have been known to cause violence, hostility and manic behavior.
Rigg said Moffitt's bizare behavior can only be linked to him being mentally ill when he killed Michael.
"The easiest thing in the world to say is this happened because he was nuts, that may or may not be insane but it certainly happened because of a mental condition."
The jury was handed the case shortly after 4:00 p.m. and deliberated until 4:30 p.m. Jurors will return Wednesday morning to continue deliberations.
