PHOENIX – Phoenix police arrested a man who allegedly shot his girlfriend's ex-boyfriend Thursday afternoon.

Daniel Patrick Aumiller, 39, was booked into the Maricopa County Jail. He faces charges of first-degree murder and possession of a weapon by prohibited person. His bond was set at $1 million.

According to court documents, Aumiller and Alan Lewis Pierce, 48, used to be friends.

Pierce's current girlfriend told police that earlier in the day he had loaded his ex-girlfriend's things into a truck and took them over to her home, but he was told that she was at Aumiller's house.

Pierce and his current girlfriend went to Aumiller's home near Campbell and 59th avenues around noon. She told police that she stayed in the truck while he went to talk to Aumiller at the front door.

The woman told police that Pierce was upset at losing his ex-girlfriend to Aumiller, according to the court paperwork. She said that Pierce called out to Aumiller to come outside and had taken off his shirt in preparation to fight him.

According to the court papers, the two men argued and Aumiller shot Pierce through the metal security door then fled the scene on a bicycle.

Police officers responded to the shooting and found Pierce in the driveway. He was transported to a local hospital where he later died.

Police reportedly found a rifle and ammunition at Aumiller's home.

Phoenix police Sgt. Tommy Thompson said several nearby schools were locked down as a precaution while officers searched the area for Aumiller.

He was taken into custody near Camelback Road and 19th Avenue at approximately 7:30 p.m. He did not want to talk to investigators.

Aumiller has four separate felony convictions. He was convicted of unlawful use of transportation, theft and endangerment in 1996; theft in 1997; misconduct involving weapons in 2001; and theft of means of transportation and trafficking stolen property in 2003.
