Officials: Deaths of mom, son were murder-suicide

OMAHA, Neb. (AP) — Investigators have confirmed that a teenager killed his mother this summer before taking his own life.

The bodies of 54-year-old Maureen Flanagan and her 18-year-old son, Cooper Flanagan, were found at their northwest Omaha home on July 16. Autopsies showed Maureen Flanagan died of blows to the head and that Cooper Flanagan, found in a car in the home's garage, died of carbon monoxide poisoning.

A statement released Tuesday by the Douglas County Sheriff's Office says the mother's skull fractures were inflicted with a hammer found in the home. It also says marijuana, alcohol, an opiate and amphetamine were found in Cooper's system.

Investigators pointed to several factors, including Maureen's declining health and Cooper's recent arrest for being a minor in possession and other counts, as possible motives.
