Police are asking for the public's help tracking down the second suspect responsible for robbing gun range customers of at least nine weapons and shooting a 67-year-old man.
Authorities identified the missing robber as 27-year-old Jeffrey Chandler.
Officials say Chandler, who stands 5-feet 10-inches tall and weighs about 200 pounds, has numerous tattoos on both arms. The most distinctive tattoo is the word - "Stretch" - located on his right hand, they say.
Investigators say Chandler fired the shot that wounded one of the victims.
If anyone sees this man, they should not approache the suspect, who is considered armed and dangerous, police said. Dial 911 immediately.
Chandler's alleged accompolice, 21-year-old Samiyyah Poteat turned herself in to authorities on June 13 after seeing herself in surveillance video of the crimes.
She faces multiple charges including attempted homicide, robbery and aggravated assault.
Officials say Poteat and Chandler were involved in two holdups at two different gun ranges -- the first at Yury's Gun Range in Philly's West Poplar neighborhood and the second at the Delaware Valley Sports Center in the city's Bustleton neighborhood.
The suspects waited in a parked car, a late model dark colored 2-door coupe, outside of the ranges until potential victims exited.
They robbed a 68-year-old man at gunpoint outside Yury's at 544 N. Percy St. around 6:40 p.m. June 11, emptying the victim's pockets and taking off with his backpack, which contained two .22 caliber handguns, according to authorities.
The following day, the pair went to Delaware Valley Sports Center at 101 Geiger Road and pulled off the same heist on an unsuspecting 67-year-old man, who was leaving the range with a friend around 8:40 p.m., according to police.
Officials say they demanded the two men hand over their cash and guns. Even though the victims were cooperating, Chandler fired a shot, striking the 67-year-old and critically wounding him, according to authorities.
Investigators also recovered the getaway car used in the crimes June 14. It was located on the 200 block of South Hanson Street in West Philly.
Detectives say Chandler is known to frequent the 4900 block of Walnut Street, as well as Willingboro, N.J. Anyone with information on his whereabouts should contact the Philadelphia Police Department's the Special Investigations Unit at the Central Detective Division at 215-686-3047 or 215-686-3048.
