A Chicago man authorities say vaulted from a balcony holding a package of “switches” used to convert Glock handguns into fully-automatic weapons during a raid is now held on $50,000 bond.

Devante Murphy, 26, of the 8900 block of South Union Avenue, was charged Wednesday with “unlawful use of a weapon/machine gun-automatic weapon.”

Investigators received information from Homeland Security Investigators that a package containing two of the automatic converter switches addressed to a residence in Calumet City were intercepted at a postal facility, the Cook County sheriff’s department said. A search warrant was executed in the 400 block of Burnham Avenue in Calumet City by Sheriff’s police, HIS and the U.S. Postal Inspection Service after the package was delivered to that address.

Murphy took off from the building during the raid, authorities said, jumping from a balcony while still holding the package of full-auto switches.

After a short chase, authorities apprehended Murphy and recovered the switches, they said.

His bond hearing was Thursday at Markham Courthouse.
