NORRISTOWN, Pa.—A Philadelphia man has waived arraignment and pleaded not guilty to charges he made an illegal "straw purchase" of a gun for another man who authorities say used the weapon to kill a suburban police officer.

The Mercury reports ( 31-year-old Michael Joseph Henry faces charges in connection with the alleged "straw purchases," in which someone legally allowed to buy firearms purchases them for someone who is forbidden from doing so. He's being held on $1 million bail.

Prosecutors say Henry purchased nine firearms and sold them to 44-year-old Andrew Charles Thomas, who was on probation.

Authorities say Thomas then used one of those guns to fatally shoot Plymouth Township Police Officer Bradley Fox during a chase after Thomas had fled from a hit-and-run crash in September. Police say Thomas then killed himself.
