NORTHGLENN, Colo. -- Neighbors of a sex offender who shot himself during a standoff with Northglenn police Monday night question why he was allowed to live just a few doors down from a middle school.

Matthew Anderson, 40, was arrested in June 2006, after talking online to a police officer he thought was a girl under 15.

An affidavit in that case shows Anderson saying, "I like kissing," "an touching," "you all over..." He also said, "is kinda illegal for
us u kno."

He got two years probation for that crime. But Monday, police came to arrest him for allegedly trying to lure another girl.

Anderson shot at police, injured one officer, then turned the gun on himself.

"My son is 14 and he goes to Northglenn Middle School. And he walks by this house every day. So it's scary to know that someone lives that close to us," says neighbor Shannon Medina.

NORTHGLENN, Colo. -- A Northglenn Police officer was recovering at home Tuesday after getting shot by a convicted sex offender while serving an arrest warrant.

The shooting happened around 6:30 p.m. Monday in the 1400 block of Bowman Place and led to a standoff that lasted until the wee hours of Tuesday morning.

Police say officers had gone to serve a warrant for criminal exploitation of a child to 40-year old Matthew Anderson, after a six week undercover sting on him. As they entered the home, Anderson fired shots at the officers.

"They knocked on the door, he didn't answer, so they breached the door," said Northglenn Police Chief Russ Van Houten. "The first two shots were then followed by at least two if not three more."

Police say Dennis Alps, an eight-year veteran of the police force, was hit in the right shoulder. A second bullet hit his body armor, saving his life.
