Victim reports his father missing. Police instead interrogated him for 17 hours, said they killed his dog, and withheld his meds from the victim. Victim tried to commit suicide in the room.

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.

Finally, after curling up with the dog on the floor, Perez broke down and confessed. He said he had stabbed his father multiple times with a pair of scissors during an altercation in which his father hit Perez over the head with a beer bottle.

Perez’s father wasn’t dead — or even missing. Thomas Sr. was at Los Angeles International Airport waiting for a flight to see his daughter in Northern California. But police didn’t immediately tell Perez.
