Chris Divello was Skinner's good friend. When she didn't show up for work at the Divello's deli, he and other friends became worried.
When police went to check the apartment, they found her dead. Her 2-year-old son was also inside. He was not injured.
Police have no suspects, but authorities want to question her ex-boyfriend and father of her child. His whereabouts are unknown.
Divello and neighbors said the two had a volatile relationship.
Skinner attended Rutgers University in Camden. She was set to graduate later this year.
Anyone with information on the killing is urged to contact Camden County Prosecutor's Office Investigator Eric Wren at (856) 225-8400 or Lindenwold Police Detective Ray Benevento at (856) 784-7566.
