A playful afternoon among friends turned fatal on March 31, 2018, when 31-year-old Daniel J. Smith of Trumbauersville Borough was shot and killed in Muhlenberg Township, Pennsylvania. Smith, a Bucks County constable and paramedic, had been horsing around with friends while helping someone move and had been firing a non-lethal airsoft gun earlier in the day. Court documents say Smith shot 21-year-old Daniel Brymer of Newtown twice with the airsoft gun and then handed it to Brymer, who placed it in his front pocket beside a real 9mm handgun Smith had previously given him.

A short time later, while outside on the lawn, Brymer reached for what he thought was the airsoft gun but instead drew a loaded 9mm and fired, striking Smith. Smith was taken to Reading Hospital and pronounced dead. Brymer was arrested the next day and charged with involuntary manslaughter and aggravated assault; he was released on $100,000 bail awaiting a preliminary hearing.

What details about that afternoon might help explain how two firearms ended up so close together?
