Owen said Adkisson apparently acted alone and chose the Tennessee Valley Unitarian Universalist Church because of recent publicity about activities there that Adkisson considered liberal.
Owen said police found Adkisson's letter in his vehicle, and that Adkisson signed it but did not address it to anyone. The letter specifically expressed hatred for gay people, Owen said.
The case is being investigated as a hate crime, police said.
Rick Lambert, the FBI agent in charge of the bureau's Knoxville office, said authorities will consider whether to bring federal charges. "Any time someone uses force to obstruct another person in the free exercise of their religious beliefs, that is a violation of federal civil rights statutes," he said.
The church, on its Web site, describes itself as a community that has worked for social change -- including desegregation, women's rights and gay rights -- since the 1950s.
"[Adkisson] indicated also in that letter that he expected to be there shooting people until the police arrived and he fully expected to be killed by the responding police," Owen said.
Investigators found 76 shotgun shells in the church, Owen said. The gunman had shot three rounds from a 12-gauge shotgun that was brought into the church hidden in a guitar case.
One of the victims, Linda Kraeger, 61, died at a hospital several hours after the shooting, Knoxville municipal spokesman Randall Kenner said.
Also killed was Greg McKendry, a 60-year-old usher and board member at the church, police said earlier in the day. Watch scene at church after shooting ยป
Five others were hospitalized in either critical or serious condition, police said.
I have a big dislike for people who hate equality.
