KNOXVILLE, Tenn. (AP) — Children from the Unitarian church where authorities said an out-of-work truck driver shot and killed two people, ended a prayer vigil by singing a song from the musical the gunman interrupted.

At the service Monday, which included candle-lighting and speeches by church leaders, the children came out singing, “The sun will come out tomorrow,” a line from the signature song in the musical “Annie.”

Gunfire erupted Sunday during the children’s performance at the Tennessee Valley Unitarian Universalist Church, which authorities said Jim D. Adkisson intentionally targeted because of its congregation’s liberal policies. A four-page letter found in Adkisson’s SUV indicated he picked the church because, the police chief said, “he hated the liberal movement.”

An overflow crowd of more than 1,000 people attended the memorial service at the Second Presbyterian Church next door.

“We’re here tonight to make sense of the senseless,” the Rev. William Sinkford, president of the Unitarian Universalist Association of Congregations, told the gathering.
