KNOXVILLE, Tenn. -- The man suspected in the deadly church shooting in Knoxville stated in a letter that he hated the "liberal movement."

The suspect, Jim Adkisson, faces murder charges and is being held $1 million bond, police said. Prosecutors said he was arraigned Sunday night.

Police have collected video cameras from people taping a children's play at a church in Knoxville, Tenn., on Sunday.

They were looking for clues into why an apparent stranger at the church opened fire, killing two and wounding seven.

Five people remain hospitalized in critical and serious condition. Two others were treated and released.

Chief Sterling Owen said Monday that police found a four-page letter in the car of Adkisson, who was tackled and held by members of the Tennessee Valley Unitarian Universalist Church after the Sunday morning attack.

Owen said Adkisson was apparently frustrated over being out of work and had a "stated hatred of the liberal movement."

The church is known for advocating women's and gay rights and founding an American Civil Liberties Union chapter.

Police said it appears that Adkisson had been plotting the attack on the church for at least a week.

Police reported that they found 76 shotgun shells at scene of the shooting, and that the 12-gauge semiautomatic shotgun used had been purchased at a pawn shop about a month ago.

A police official said the suspect "expected to be in there shooting at people until police arrived" and that he apparently expected "to take a lot of casualties." Police also said the suspect "fully expected to be killed by the police."

Police said the suspect, who has no known family or next of kin, appeared frustrated by his failed attempts to find a job and apparently blamed liberalism. He also indicated in the letter that his food stamps were being reduced or cut off.

A neighbor called him a "really, really nice guy" who often worked on his motorcycle and would take long weekend trips. She said she doesn't think he's had steady work for a few months.

Witnesses said the gunman started firing as children were performing a play at the church.

Church usher Greg McKendry, who died from a shotgun blast, is being praised as a hero for shielding others. Linda Kraeger died a few hours later.

No children were injured.

The FBI is assisting in the investigation, which is being treated as a hate crime. One witness said the gunman shouted "hateful" words before opening fire.

A neighbor said the 58-year-old was known to speak often about his parents and that he said they forced to him to attend church "all his life."
