Man accused of stabbing his mother to death

LITTLETON, Colo. – A woman is murdered, stabbed to death inside a Littleton home and now her son is facing murder charges.

30-year-old Darin Ninneman is in Arapahoe County Jail charged with second degree murder.

Just after 6:00 Saturday night, neighbors and friends on the 5600 block of Windermere Street heard a woman scream and ran outside to see what had happened.

“I don’t know how do you do that to anybody, let alone your own mom,” says Nick Romano, the victim’s landlord and owner of Romano’s Italian Restaurant next door.

Romano says the victim’s name is Lorri. He says Ninneman stopped by the home on Windermere Street to visit his mother Saturday evening.

According to witnesses, the two got into an argument when Ninnemen started to attack his mother.

“It wasn’t big commotion. There wasn’t a huge argument. Her son just kind of lost it grabbed a knife in the kitchen and started stabbing his mom,” Romano continues.

Friends and neighbors tried to keep Lorri alive and called 9-1-1.

“My friend was there. He tried to help towel over her and tried to stop the bleeding,” says Romano.

Covered in blood, witnesses watched as the suspect, Darin Ninneman ran from the house.

“They caught the kid pretty quick so he wasn’t very far away,” Romano adds.

Ninneman is described as a troubled man with a long history of drug abuse.

“This was her son who evidently recently got out of rehab,” says neighbor, Tom O’Brien.

“He’s not all there. He’s not right in the head right. Obviously,” says Romano.

Darin Ninneman has been arrested for drugs, larceny and assault since 2009 and has served more than 2-1/2 years in jail.
