DALLAS -- A United Methodist minister who attempted suicide after an attack on his wife says he did nothing to hurt her and wishes police would find the culprit.

The Rev. Walker Railey, who reported receiving threatening letters before the attack, also said he received several death threats after being admitted to a psychiatric hospital after his suicide attempt.

He spoke to reporters after leaving the hospital last week.

Railey was senior minister of the downtown First United Methodist Church of Dallas when his wife was nearly choked to death in the garage of their home early April 22. She remains in a coma and is virtually brain-dead.

Earlier this year, Railey, 39, said he and his family were targets of threatening letters linked to his stance against racial injustice. In the pulpit Easter Sunday, Railey wore a bulletproof vest and his family was given police protection.

Police said the letters were written on a typewriter in Railey's church.

"I didn't write those letters to myself. I've never been accused of being overly smart, but I'm not totally dumb. I wouldn't write letters to myself on a typewriter in my own church if I did it," he said.

Railey said the FBI had tapes of telephone threats made to his home while he was hospitalized and a handwritten death threat mailed from out of state. He said the letter referred to his views in favor of civil rights and was similar in tone to others he received before the attack on his wife.
