The new witness disclosed he also was “a victim of sexual abuse by Martinez while being a foster child,” Gregory wrote.
The witness told police he and Martinez drove to Tooele, Utah, earlier this month, according to the affidavit. He told police the teenager was living there in the home of a friend of Martinez. He told police Martinez was paying the friend.
He told police he slept on a couch in Utah, but Martinez and the teenager “slept in a bedroom behind a locked door together,” according to the affidavit.
The witness also told police Martinez took a .38-caliber handgun when they went to Utah, according to the affidavit. The witness said the teenager sent text messages last week that he was scared and wanted to leave the house in Utah, according to the affidavit.
Police reported they arrested Martinez on Friday at SE 44 and Sooner Road after he was led to believe he was going to a covert meeting with the witness. Police said he did not have a gun at the time of his arrest.
District Attorney David Prater said Friday the case against Martinez has improved significantly because of the new information from the witness.
“The activity that will come out … at preliminary hearing will amaze the public,” the prosecutor said, “They will truly see what kind of a person Mr. Martinez is.”
The investigation has had several twists since the officer was first arrested in January.
Police earlier reported they found numerous photos on a computer in the officer's home of children in his care in “various stages of undress.” Several were posing in a mirror, police reported.
Police also reported finding hundreds of photos of homosexual pornography on the computer.
