A 40 year old ex-army soldier has been identified as the shooter in the Sikh temple massacre, sources have told Fox News.

Wade Michael Page was, at one time, attached to Fort Bragg and is said to be "heavily tattooed." There are few other details about him, but a search warrant was served at an apartment building where the alleged shooter lives.

The man authorities say killed six in a Milwaukee-area Sikh temple before police shot him was a heavily-tattooed, 40-year-old ex-Army soldier, sources told Fox News, but what triggered his rampage remains unclear.

Sources identified the dead suspect as Wade Michael Page, who was at one time attached to the Fort Bragg Army installation in North Carolina. Local authorities have scheduled a 10 a.m. press conference, where more details may emerge about Page and what the FBI is treating as an act of domestic terrorism in the temple, in the Milwaukee suburb of Oak Creek. Six people were killed and four wounded, including a police officer, before the man being identified as Page was shot dead by a police officer.

Satwant Kaleka, president of the temple, was one of those shot. Sources told Fox News he attempted to tackle the suspect as he sprayed gunfire inside the temple.

Late Sunday, the investigation appeared to move beyond the temple as police, federal agents and the county sheriff's bomb squad swarmed a neighborhood in nearby Cudahy. Bureau of Alcohol, Tobacco, Firearms and Explosives agent Tom Ahern said warrants were being served at the home of the shooter.

Prior to starting the search at the 3700 block of Holmes Ave., police asked two blocks of residents to leave the area or remain indoors. FBI agents are there with an armored truck, a trailer and other vehicles. Other law enforcement officers are there too, along with a police dog.

A neighbor says he had a recent break up with his girlfriend:

A woman who says she was a neighbor of the suspect tells FoxNews.com that last week she heard yelling coming from the apartment she believes is the same one the FBI is now searching.

The neighbor says, as she understood it, the suspect had lived in the apartment with his girlfriend until their recent break-up. The suspect had then moved into another apartment nearby two weeks ago. She says he had returned to the old apartment and was banging on the door of his old apartment, demanding to be let in. The neighbor also said she believed the suspect had a 9-11 tattoo.

Another local resident Kurt Weins told the Journal Sentinel he rented out the upper flat of the duplex to a man in his 40s. 

"I had him checked out and he definitely checked out," Weins told the newspaper. "The cops told me they don't want me to say nothing right now."

We'll have an update in a few hours after a police briefing at 9:00 AM central time.
