Another cat owner who did not want to be identified because she does not want to be a victim of retaliation says her cat, a 13-year-old Siamese named Rayden, was found dead Wednesday a mile and a half in the hills above her home.
"His face was crushed, his jaw was crushed," she said. "There were no animal bites or puncture wounds."
The San Jose Police Department's Assault Unit is now actively investigating.
"We are canvassing neighborhoods looking for surveillance videos, interviewing victims and interview any other leads that may come about," said Cruz.
If you have a cat that's missing in that area please call police.
