A Colorado man has confessed to shooting and killing two teenage boys who allegedly tried to blackmail him for $20,000 with a video of him asking a boy for sex, according to a police affidavit.
The accused murderer is William Otto, 43, of Adams County, Colo., and the victims are Gustavo "Danny" Espinosa-Gamboa, 16, and Jonathan Gonzalez, 15.

The boys were last heard from on Friday and when Gonzalez's sister couldn't find him, she spoke to some of the boys' friends who told her that Gustavo and Jonathan had recorded a video on Gustavo's phone of a man in the neighborhood named "Billy" who Gustavo and his friends frequently visited, the affidavit said. Billy would turn out to be William Otto, according to the police.

A friend of the boys told police that Otto was known to allow teenage boys from the neighborhood to come to his house and drink alcoholic beverages, the document states.

Gustavo's friends said that, "the video was of Billy asking Gustavo Espinosa-Gamboa to let Billy perform oral sex on Gustavo Espinosa-Gamboa. The video also showed Billy touching Gustavo Espinosa-Gamboa inappropriately," the police report states.

The boys' friends said that Gustavo and Jonathan's plan was to "show the video to Billy and blackmail him for money over the video."

Police said that when authorities responded to Otto's home, they knocked several times on the front door and rang the doorbell, but there was no answer.

"Deputy Temple said that it appeared the hallway carpet had been removed but could not tell if it had been done recently," the report said.

On Sunday, Otto showed up at the Adams County Sheriff's substation with a couple, Kevan and Carol Johnson.

Kevan Johnson told police that he worked with Otto at Harlan Bakeries where Otto was employed as the maintenance manager, the police report states.

Johnson said that Otto had called him that day to say that he had done something bad, police said.
