Two men, including a Philadelphia Police officer, are in the hospital after two violent robberies and another man is dead.

The violence began in the Society Hill section of the city shortly before 10 p.m. Police say a man walking home was shot during a robbery on Lawrence Street near 4th and Pine.

The victim, who has not yet been identified, was taken to Jefferson Hospital where he is in stable condition with a gunshot wound to the shoulder. Police say the victim is a pharmacist at a CVS Pharmacy in Queen Village and its possible he was followed home from work.

Surveillance video shows the victim chasing the suspect after his iPhone was taken. Moments later the suspect opened fire. No arrests have been made.

A short time later across the city an off-duty police officer was tabbed as he walked along the 4900 block of Grant Avenue in Northeast Philadelphia near the Torresdale Rail Station. Police say he was approached by two men who struck the officer in the head and then stabbed him twice in the stomach before fleeing on Grant towards a wooded area.

The officer was taken to Aria Torresdale Hospital in stable condition. Police say the officer is 28 years old and a two-year veteran of the police force. The suspects stole his iPod and an undisclosed amount of cash.

Then, just before 2 a.m., three men knocked on the door of a home on the 5700 block of Leonard Street in the Wissinoming section. A woman opened the door and began arguing with the men. Her husband, 29-year-old Lamar Muldrow, came to try and push the men out when one of them opened fire, killing Muldrow, according to Philadelphia Police.

"The victim was struck, tried to run upstairs and was struck again," said police Capt. George Fuchs. "Supposedly the males continued to firing as they back away from the house.

The shooting could have been worse considering as many as eight people, including teens, were in the home at the time, according to investigators. Police say the motive in the shooting was robbery.
