ARVADA, Colo. (KDVR) — Donovan Walsh was arrested in Arizona on Sunday in connection to the death of his ex-girlfriend, Alicia Banks-Newton, in Arvada.
According to the Arvada Police Department, about 2:15 p.m. Friday, officers conducted a welfare check on 32-year-old Banks-Newton.
The welfare check came after Walsh’s mother contacted his probation officer saying Walsh may have killed Banks-Newton, according to an arrest affidavit.
APD drafted a warrant and searched Banks-Newton’s apartment at 7655 W. 67th Ave.
Banks-Newton was not found inside, but APD “discovered concerning physical evidence.”
According to the affidavit, investigators found significant evidence of foul play in the apartment, including blood and bleach.
On Sunday, APD detectives requested and received a warrant for 43-year-old Walsh’s arrest for first-degree murder, tampering with evidence and domestic violence.
His mother, who lives in Arizona, said Walsh showed up at her home with a vehicle she did not recognize and at least one dog belonging to Banks-Newton. He also reportedly admitted to stabbing Banks-Newton.
According to Walsh’s mother, he became upset in April after learning that Banks-Newton’s child was not his.
Walsh was found near Globe, Arizona on Sunday and taken into custody without incident.
Banks-Newton’s body has not been found.
According to court records, Walsh has a significant criminal history, including domestic violence crimes in which Banks-Newton was the victim. Banks-Newton had also previously requested a restraining order against Walsh.
The investigation is ongoing.
