Police on Thursday released surveillance video of the events Sunday night leading up to the fatal shooting of 26-year-old Amber Long.

Long was walking with her mother on the 900 block of North Front Street in Northern Liberties when, shortly after 10:30 p.m., two unknown men approached and tried to grab both women's purses. One of the men fired a shot, striking Amber in the chest. She died at Hahnemann University Hospital.

The suspects were last seen fleeing north on Front Street in a newer model, possibly four-door Chevrolet Impala. That vehicle was caught on camera and released to the public, along with portions of the purse-snatching.

Authorities are offering a $30,000 reward for information leading to the arrest and conviction of Long's killers. As with all homicides, the city of Philadelphia is offering a $20,000 reward, while the Fraternal Order of Police has contributed $10,000.

Police on Tuesday announced the arrest of a 43-year-old Lamar Beatty, who was charged with allegedly making false reports to law enforcement. Beatty is accused of giving detectives a bogus tip that led them to take two men into custody for questioning. Both men were released after investigators found they had nothing to do with the slaying.

Anyone with information on the suspects or crime is asked to contact the Homicide Unit at 215-686-3334 or 3335, or to submit an anonymous tip by dialing 215-686-TIPS (8477), texting PPD TIP (773847) or by filling out this online form.
