Philadelphia (CBS) – Philadelphia police are investigating a number of homicides that took place from late Saturday afternoon, through early Sunday morning.

As 2011 neared a close, there were three homicides. Late Saturday afternoon a 26-year-old man was shot in the city’s Hunting Park neighborhood. Then, just before midnight, a couple was found shot and killed inside a car in the Olney section marking the end of a violent year in the city with a total of at least 328 homicides.

The first of 2012 occurred shortly after midnight. A 77-year-old man was found stabbed to death inside a home in South Philadelphia. One man has been arrested in that case.

Around 1:30 a-m, police say a man was fatally shot following a car crash in the Frankford section of the city.

Just over an hour later, a 23-year-old man was found with a gunshot wound and later died at the hospital.
