A pair of Englewood brothers are in jail on sexual exploitation of a child charges after police found children’s underwear in their home and child pornography on their computers, police reports said.

Daniel Paul Alberts, 65, and Timothy M. Alberts, 61, each were charged Saturday with one count of sexual exploitation of a child, according to their arrest warrants. Both are being held in the Arapahoe County Dentention Center on $50,000 bonds, according to the jail’s website.

Timothy Alberts has a criminal history of being a child predator. He first was arrested for child sex assault in 1982 by Boulder police and was sentenced to three years of probation, according to Colorado Bureau of Investigation records. He also was found guilty in 1989 of sex assault in Adams County and sentenced to a year in jail, records show.

Englewood police were called to the Alberts’ home on the 3900 block of South Washington Street on Saturday morning after a woman said she had been assaulted and locked in a shed in their backyard. When officers arrived, they reported “a nearly unbearable odor coming from inside the house,” the Alberts’ arrest warrants said.

Inside, police found the Alberts’ 91-year-old father living in “extremely filthy conditions,” the warrants said. The home was infested with rats, mice, maggots and insects, a police department news release said.

The father was sitting under a blanket in a chair and watching television. He was removed from the house and taken to a hospital for treatment, the warrant said.

The Alberts gave officers consent to search the house, and those officers found boy’s underwear displayed on a wall in a basement bedroom. Other children’s undergarments were on the floor, the warrant said.

In an upstairs bedroom, police also found children’s underwear and multiple computers and other electronic hardware running, the warrant said. Investigators obtained a search warrant for the house and found sexually explicit photographs on the computers.

While being interviewed at the police station Timothy Alberts told investigators that he and his brother were pedophiles and that they looked at pictures on their computers and watched videos in their bedrooms, the warrant said.

The home has been condemned by the Englewood Building Department, police said.

The police investigation is ongoing.
