According to court records, detectives told Perez that his father was dead, that they had recovered his body and it now “wore a toe tag at the morgue.” They said they had evidence that Perez killed his father and that he should just admit it, records show.

Perez insisted he didn’t remember killing anyone, but detectives allegedly told him that the human mind often tries to suppress troubling memories.

At one point during the interrogation, the investigators even threatened to have his pet Labrador Retriever, Margosha, euthanized as a stray, and brought the dog into the room so he could say goodbye. “OK? Your dog’s now gone, forget about it,” said an investigator.
