MIAMI, Florida (CNN) -- A judge in Miami allowed the supervised release of a man charged with 19 counts of animal cruelty Wednesday, saying a psychiatric evaluation showed he is competent and not a danger to himself or others.

Tyler Hayes Weinman, 18, also is charged with 19 counts of improper disposal of dead animals and four counts of burglary linked to a monthlong killing spree of pet cats in the Miami area, police said.

Pet owners and police began discovering disfigured cats May 13. One pet owner, Donna Gleason, told CNN that her family cat, Tommy, was "partially skinned" and left dead in her yard.

Police said 34 cats have been found dead in the towns, but only 19 mutilated cats could be linked to a serial killer. Police confirmed that some of the cats were killed by dogs, said Maj. Julie Miller of Cutler Bay police.

Weinman, who works odd jobs but spends most of his time at home and unemployed, had been a person of interest for several weeks, Miller said. He was arrested Saturday.
