An Oregon man is accused of sex crimes involving two teenagers and a 4-year-old girl, and police say he used the Internet to line up people to have a group sex with one of the victims.

Darrin Vaughn Daily, 44, of Newberg, faces numerous charges and is being held on $1 million bail in the Yamhill County Jail.

Sgt. Tim Weaver of the Newberg-Dundee Police Department said investigators searched Daily's apartment and seized evidence after a 15-year-old disclosed last month that Daily had sex with her after providing marijuana and alcohol.

Investigators soon learned that another girl, 14, accused Daily of sexually abusing her and photographing it. The girl told them Daily had at times tied her up and forced her into group sex with the men he solicited on the Web site Craigslist.

The girl also told police Daily photographed her having sex with his dog.

Weaver said detectives who analyzed Weaver's computer found images of the girl having sex with adults and the dog. Images of a 4-year-old girl being sexually abused were also found.

Weaver told The Oregonian newspaper he had never seen such a case in more than three decades as a police officer.

"This is certainly at the top of the list of hideous crimes," he said

Police were able to find the 4-year-old, and she told investigators that Daily sexually abused her. She is being cared for at a child abuse assessment center, according to a police statement.

The three men accused of responding to the Craigslist ad and taking part in the sex abuse are Patricio Moreno, 43, of Forest Grove; Robert D. Thompson, 34, of Portland; and David Garcia, 41, of McMinnville. They also were jailed in Yamhill County, although Garcia posted bail.

Police also seek a woman accused of sexually abusing one of the girls.

Daily is accused of rape, sodomy, sex abuse, sexual assault of an animal, delivery of marijuana to a minor, online sexual corruption of a child, endangering the welfare of a minor and using a child in a display of sexually explicit conduct.

Thompson, Garcia and Moreno are all charged with sex abuse and third-degree rape. Thompson faced an additional charge of using a child in a display of sexually explicit conduct, while Moreno is accused of sodomy.
