(CBS/AP) OAK CREEK, Wis. - The suspect in a shooting that left six people dead at a Sikh temple in suburban Milwaukee on Sunday, and who himself was killed by police, has been identified as Wade Michael Page, who served in the U.S. Army for about six years.
According to sources in the Army, Page enlisted in April 1992 and was given a less-than-honorable discharge in October 1998. He served at Fort Bliss, Texas, in the psychological operations unit in 1994, and was last stationed at Fort Bragg, N.C., attached to the psychological operations unit. The details of his discharge were not immediately clear.
Wade was killed outside the temple in a shootout with police officers after the rampage that left terrified congregants hiding in closets and others texting friends outside for help.
Officials had previously described the suspect as a heavy-set, 40-year-old Caucasian with numerous tattoos.
Sources tell CBS News some unspecified evidence suggests race or ethnicity may have played a role in the violence, but no links to extremist groups have been confirmed.

Local police called the attack an act of domestic terrorism, but other sources tell CBS News correspondent Bob Orr it may be more accurate to refer to "an investigation into a possible hate crime."
Neither local nor federal sources provided further details or suggested a possible motive, including whether the suspect specifically targeted the Sikh temple.
The bodies of the victims are with the Milwaukee County Medical Examiner, reports CBS Affiliate WDJT. Autopsies will be performed today.
Oak Creek Police will hold a media briefing at 11:00 a.m. ET Monday.
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, evacuating several homes and searching a duplex. Bureau of Alcohol, Tobacco, Firearms and Explosives agent Tom Ahern said warrants were being served at the home of the gunman.
Records show that Page was the registered inhabitant at an apartment in South Milwaukee from December 2011 until the present.
CBS News correspondent Ben Tracy reports Page is only believed to have lived at the residence for two weeks, according to neighbors.
"Nobody has really seen him," neighbor Alma Rayes tells CBS News. "We heard here and there that they've been doing a lot of arguing, between him and another female, but I haven't seen him."
"He did not speak, he just began shooting," said Harpreet Singh, relaying a description of the attack from the wife of his uncle, temple president Satwant Singh Kaleka.
Singh said Satpal Kaleka told him she was in the front room when the shooter walked in. She said the 6-foot-tall bald white man — who worshippers said they had never before seen at the temple — seemed like he had a purpose and knew where he was going.
Oak Creek Police Chief John Edwards said police expected to release more information Monday. He said the FBI will lead the investigation because the shootings are being treated as domestic terrorism, or an attack that originated inside the U.S.
"While the FBI is investigating whether this matter might be an act of domestic terrorism, no motive has been determined at this time," Teresa Carlson, Special Agent in Charge with the agency's Milwaukee division, said in a statement Sunday night.
Edwards said the gunman "ambushed" one of the first officers to arrive at the temple as the officer, a 20-year veteran with tactical experience, tended to a victim outside. A second officer then exchanged gunfire with the suspect, who was fatally shot. Police had earlier said the officer who was shot killed the suspected shooter.
Sikh rights groups have reported a rise in bias attacks since the Sept. 11 terrorist attacks. The Washington-based Sikh Coalition has reported more than 700 incidents in the U.S. since 9/11, which advocates blame on anti-Islamic sentiment. Sikhs are not Muslims, but their long beards and turbans often cause them to be mistaken for Muslims, advocates say.
Even though the gunman's motives were a mystery Sunday, Kaur said the shootings reopened wounds in a community whose members have found themselves frequent targets of hate-based attacks since Sept. 11.
"We are experiencing it as a hate crime," she said. "Every Sikh American today is hurting, grieving and afraid."
