State police received a tip and arrested him in a North Huntingdon Township Walmart parking lot when the heroin fell from his lap onto the passenger side floor of the car he was in.

Murphy was the sixth suspect Monroeville Police were looking for in connection with a shooting that took place outside Monroeville mall in April.

Authorities said two rival gangs from McKeesport began fighting at the mall. The brawl eventually spilled outside, where one person pulled out a gun and 14 shots were fired.
