MOUNTAIN LAKES — The 39-year-old man who shot and killed his co-worker inside of a Mountain Lakes realty office Friday night told police he would shoot anyone who approached him and appeared determined to end his life, according to a chilling 911 tape released this morning by the Morris County Prosecutor's Office.

Leonardo Parera: "I just killed someone, uh 100 Route 46 ."

911 dispatcher: "What do you mean you just killed someone?

Parera: "Exactly what I said I'm armed and dangerous."

Parera, 39, shot and killed secretary Christine Capone King around 4:44 p.m. and then died after a gun battle with police in a parking lot outside of a Exit Gold Realty Service in Mountain Lakes Friday night, according to Capt. Jeff Paul, spokesman for the Morris County Prosecutor's Office.

It remains unclear why he shot the woman.

After talking with the dispatcher, Parera became impatient with the dispatcher's questions.

"You know what, I’m armed, I’m dangerous, send the cops out. I’m in a parking lot. I can see from every angle I will shoot at anyone who approaches the car ," Parera told the dispatcher.

Parera's comments indicate he fully expected to be killed by police.

“You know what, I need to make some calls and let people know I’m going to be dead now.” he said. “Tell the officers that I don’t want to kill anybody else.”
