Martinez has taken care of dozens of foster children, all boys, over the past decade.
A confidential informant who is not identified in the affidavit told officers Salazar was the person who sneaked into Martinez's home while it was under police guard during a break in the search of the residence, Hurst wrote. The informant told police Salazar broke into the home at Martinez's direction.
The informant also told police Martinez orchestrated the videos of the accuser saying he lied to police, according to the affidavit.
Another former foster child, Troy Dobbs, 18, of Fort Drum, N.Y., corroborated the informant's statements when police went to New York to interview him. Dobbs said he took the accuser to a fast-food restaurant, where Martinez pressured the boy to recant on video.
Dobbs also told investigators Salazar was the person who burglarized Martinez's home and that Salazar took some evidence and planted other things, Hurst wrote. Dobbs told police the accuser and other children had described to him abuse by Martinez before.
Salazar told The Oklahoman in January he was never in Martinez's official custody but that Martinez took him into his home when he was a teenager and provided him guidance. He said he supports Martinez and thinks he's innocent. Salazar has previous felony convictions for unauthorized use of a motor vehicle and concealing stolen property, court records show.
Salazar was arrested as an accessory after the fact on complaints of lewd acts with a child, lewd or indecent proposals or acts to a child younger than 16 and allowing abuse by a caretaker, according to the affidavit. He has not been charged. He was released on $40,000 bail, jail records show.
Efforts to reach Martinez were not successful Monday. Martinez was released on bail shortly after he was arrested and remains on paid administrative leave from his job as a patrol officer in south Oklahoma City.
All of the children in Martinez's care were removed from his home after his arrest.
