KNOXVILLE, Tenn. – An out-of-work truck driver accused of opening fire at a Unitarian church, killing two people, left behind a note suggesting that he targeted the congregation out of hatred for its liberal policies, including its acceptance of gays, authorities said Monday.

A four-page letter found in Jim D. Adkisson’s small SUV indicated he intentionally targeted the Tennessee Valley Unitarian Universalist Church because, the police chief said, “he hated the liberal movement” and was upset with “liberals in general as well as gays.”

Adkisson, a 58-year-old truck driver on the verge of losing his food stamps, had 76 rounds with him when he entered the church and pulled a shotgun from a guitar case during a children’s performance of the musical “Annie.”

Adkisson’s ex-wife once belonged to the church but hadn’t attended in years, said Ted Jones, the congregation’s president. Police investigators described Adkisson as a “stranger” to the congregation, and police spokesman Darrell DeBusk declined to comment on whether investigators think the ex-wife’s link was a factor in the attack.

Adkisson remained jailed Monday on $1 million bond after being charged with one count of murder. More charges are expected. Four victims were hospitalized in critical condition.
