LAKEWOOD, Colo. — Court documents released Monday reveal the suspect in the death of a 2-year-old in Lakewood last month had become increasingly odd and paranoid.

Roman Morales, 21, is being held without bond, charged with first-degree murder in the death of 2-year-old Donnie Romero, his cousin.

The arrest affidavit says the toddler’s body was found beneath a pillow and blanket in a plastic storage tote in the living room, an electrical cord wrapped several times around his neck.

The toddler and his mother were living with relatives at an apartment in Lakewood and the mother asked Morales to keep an eye on the child while she took a shower.

The arrest affidavit says there were three other adults in the apartment at the time. One says he heard the little boy choking, but Morales told him it was on a piece of candy and the child was fine.

Another says she saw Morales pushing a blanket into a storage tote but he told her he was just soaking up water. No one realized anything was wrong until it was too late.

Relatives say they were worried about Morales’ mental health because he kept talking about government conspiracies to kill citizens, secret codes, and claimed the FBI and mafia were monitoring their phones and computers.

Just before he was arrested at police headquarters, court documents say Morales had a bizarre conversation with his mother about his daughter. He whispered to her “they were going to hurt her. I did what I was told to do.”
