MESA COUNTY, Colo. -- A Colorado teenager who was arrested in murder of his ex-girlfriend admitted to killing her because he was "upset" over their breakup, an affidavit states.
Tanner Flores, 18, was arrested last week after sheriff deputies found the body of Ashley Doolittle, 18, KDVR reports.
Doolittle had recently ended a one-year relationship with Flores, an affidavit says.
Flores was reportedly distraught over the breakup.
"Tanner was 'upset' over the breakup with Ashley," a friend of Flores told law enforcement, according to the affidavit. "Another friend stated that Tanner was 'really down' over the breakup and did not know why they were no longer together."
According to KDVR, Flores told investigators he shot his ex-girlfriend twice in the head near Carter Lake because he was upset with her.
He then reportedly cleaned her body at his late grandfather's home and put the body back into his truck.
A neighbor told investigators that she saw Flores' vehicle in the driveway.
When authorities arrived, they found Doolittle's body in the back of Flores' truck, KDVR reports.
The teen was arrested and is being held on suspicion of first-degree murder and second-degree kidnapping.
