The gunman in the shooting at Los Angeles International Airport on Friday is originally from South Jersey.

23-year-old Paul Ciancia grew up in Pennsville, Salem County, N.J., according to the town's police chief.

Authorities say Ciancia pulled a semi-automatic rifle from a bag and shot his way past a security checkpoint at Los Angeles International Airport on Friday, killing a TSA officer and wounding two other people.

A law enforcement official said the Ciancia was wearing fatigues and carrying a bag containing a hand-written note that said he "wanted to kill TSA and pigs."

The suspect is in custody after apparently being wounded in an exchange of gunfire with officers.

Police say the shooter's brother got a text message from Ciancia today saying he was thinking about taking his life.

The brother contacted Pennsville Police and around 1 p.m. Pennsville's police chief called Los Angeles Police to do a well-being check on Ciancia, police said.

Los Angeles Police went to Ciancia's apartment. The man wasn't there, but his roommates told police everything was fine, authorities said.

Pennsville Police say they have not had any prior dealings with Ciancia.
