New Jersey Gov. Phil Murphy issued a statement expressing sympathy for the victims and their families and calling for stricter gun safety measures.

"Let there be no mistake: This despicable and cowardly act of gun violence only steels our commitment to ensuring New Jersey leads the nation in passing and enforcing strong and commonsense gun safety laws," Murphy said. "No community should ever experience what occurred last night in Fairfield."

"Our thoughts and prayers go out to all those injured and killed overnight in the mass shooting in South Jersey," the State Police Benevolent Association tweeted. "Too many lives have been lost around this State this weekend by the rising violence."
