PHILADELPHIA (WPVI) -- Just hours after announcing an arrest in the murder of a store clerk in Philadelphia's Frankford section, police say they are now looking for a second suspect.
He is identified as Siddeeq Shakoor, police said Tuesday afternoon.
Police say Shakoor is known to frequent the 5600 block of Windsor Street and the 4800 block of Mulberry Street in Philadelphia.
He is considered to be armed and dangerous.
On Tuesday morning, police announced the arrest of 37-year-old Kharee Simmons.
He is being charged with murder, criminal conspiracy and robbery, among other offenses.
The deadly shooting happened last Thursday morning .
Investigators said the victim was discovered just after 12:30 a.m. inside the Frankford Convenience Store at the intersection of Frankford Avenue and Pratt Street.
Officers learned about it when someone told an officer who was patrolling the area that a man was shot inside the convenience store.
Police rushed the victim to Temple University Hospital, where he was pronounced dead.
The victim has since been identified as 37-year-old Kenneth Kennedy-McLeod.
Police say at least five shots were fired from a semi-automatic weapon, and that the shell casings were found just a few feet from an employee section where Kennedy-McLeod was found.
The cash register was open and money was all over the floor, investigators said.
Action News spoke to a woman last week who said she knew the victim.
"Very friendly, loving, caring. He was a loving person. He was my buddy," said Shirley Jones, of Frankford.
"It wasn't worth his life. He would have gave it up to him. He would have gave it to him. It's just sad," she said.
