Updated at 8:00 a.m. Eastern, CBS news(CBS/AP) OAK CREEK, Wis. – The suspect in a shooting that left six people dead at a Sikh temple in suburban Milwaukee on Sunday has been identified as Wade Michael Page, who served in the U.S. Army for about six years.

According to sources in the U.S. Army, Page enlisted in April 1992 and 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, North Carolina, 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 Bon Orr it may be more accurate to refer to “an investigation into a possible hate crime.”

Neither the local nor the federal sources provided further details or suggested a possible motive, including whether the suspect specifically targeted the Sikh 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, evacuated several homes and searched a duplex. Bureau of Alcohol, Tobacco, Firearms and Explosives agent Tom Ahern said warrants were being served at the home of the gunman.

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
