PITTSBURGH — Police in Pennsylvania say a gun dealer has been sentenced to prison for threatening an animal welfare officer, and now more charges have been filed after officers removed nearly 600 weapons from his home.

The Allegheny County Sheriff’s office said Gary Guyaux put officers and neighbors in danger. He’s a licensed firearms dealer, but officers in July found four weapons that had been stolen and 15 that were prohibited.

Guyaux was sentenced to 18 to 36 months on Thursday on the earlier charge of terroristic threats.

He was arraigned on the new charges including receiving stolen property Wednesday.

The ordeal started in 2014 when an animal welfare officer cited him for the 36 dogs on his property.

Guyaux is heard in recordings saying he wanted to kill the man.

His attorney says the district attorney’s office is unfairly targeting his client.
