Prosecutors said a major break in the difficult investigation came April 14 when the former foster son came forward because of concerns Martinez was going to hurt his chief accuser, the adopted son who first reported sexual abuse.
Martinez was rearrested April 15 because of the new information.
The former foster son, now 21, told police he witnessed Martinez sexually abuse three adopted sons “all while they lived with Martinez in Oklahoma City,” police reported.
The former foster son also said Martinez molested him, too, while he was in foster care there, police reported.
The former foster son said he traveled with Martinez this month to Tooele, Utah. He told police that he slept on a couch there, but Martinez and his chief accuser “slept in a bedroom behind a locked door together,” police reported.
Police reported the former foster son and another witness said Martinez had threatened to kill his accuser numerous times. Police reported the two also said they heard Martinez threaten to kill a church elder, police detectives “and anybody who ‘snitches' on him.”
“The threats were detailed as to shooting them and or putting a bullet in their head,” police reported. “Martinez has also made numerous statements … he would also take his own life.”
Police reported the former foster son also said he was offered a down payment on a car if he would lie to police and claim he was the one who looked up the child pornography found on the officer's computers.
In a court affidavit, police reported five boys related how they were physically abused by other boys in the home, but the officer would do nothing. One boy told police he was kicked, punched and “made by the other foster kids to run around naked,” police reported. Another boy said other boys hit him and tied him to a bed.
