Four people were stabbed over a 24-hour period this weekend in Philadelphia and motives for the violence range from broken hearts to fights, according to police.

The latest stabbing occurred around 3:30 a.m. inside of the Moonlight Cuisine Restaurant Lounge on Limekiln Pike near Haines Street in West Oak Lane.

Police said a 29-year-old man was stabbed twice in the left side of his chest by another patron he was fighting with inside of the lounge. The victim was taken to Einstein Medical Center in critical condition. The suspect remains on the loose. Police described him as a black man with a Jamaican accent who is 5-foot-10 and weighs between 160-and-180 pounds.

Love gone awry appears to be behind another stabbing that police responded to this weekend in the city. Around 3:09 a.m. Saturday, a 36-year-old man who was at his house on Market Street near 57th in West Philly with an "unknown female companion" received a surprise phone call from his ex-wife, who asked him to go to the front door of his house "so they could talk," police said.

Although everybody knows that nothing good happens with an ex after 2 a.m., the man went to his front door anyway, and when he opened it, his ex-wife stabbed him once in the shoulder with a steak knife, police said.

The victim was taken to Penn Presbyterian Medical Center for a large cut to his shoulder, but he is listed in stable condition, according to authorities.

The identity of the man's ex-wife, who ran away from the scene and has yet to be apprehended, has not been released.

Finally, police have yet to release the motive or the name of a suspect in two separate stabbings that were believed to have been committed by the same man early Saturday morning.

At 4 a.m. that day, cops responded to 17th and Walnut streets in Center City where they encountered a 31-year-old man who told them, just before he passed out, that he'd been stabbed in the stomach at 13th and Walnut streets. That man was taken to Hahnemann University Hospital, where he is listed in critical condition.

Meanwhile, officers who responded to Jefferson University Hospital took a report from another stabbing victim, a 27-year-old man who said that he was stabbed twice in the stomach by a man he had an altercation with on St. James Street near 13th, right around the corner from where the other stabbing allegedly occurred.

The condition of the second victim was not immediately available.

Police said they are only looking for one offender in both cases. They described the suspect as a caramel-complexioned black man with a medium build who is about 23 years old and around 5-foot-7. He wore a purple-hooded sweatshirt and a tan jacket, according to authorities.

Anyone with information about any of these cases is urged to call the department's tip line at 215-686-8477.
