Rebekah Gay Murder: Pastor, who is an ex-con, admits to killing Mich. mom as part of sex fantasy, reports say

(CBS/AP) BROOMFIELD TOWNSHIP, Mich. - An ex-convict has confessed to beating and strangling his 24-year-old neighbor as part of a sexual fantasy, hiding her body, and then returning to her home and helping her three-year-old son get costumed for Halloween, authorities said Thursday.

John D. White was arraigned Thursday on first-degree murder charges and ordered jailed without bond.

According to an affidavit that was used in his arrest warrant, White admitted that for two weeks he thought about killing Rebekah Gay and having sex with her dead body.

White told investigators he went to Gay's trailer about 2 a.m. Wednesday, struck her head repeatedly with a mallet, then strangled her with a zip tie. He said he stripped her body but did not remember carrying out a sex act.

Authorities say White led them to Gay's body, half a mile from the home in Isabella County's Broomfield Township.

Isabella County Sheriff Leo Mioduszewski told reporters that White had known Gay for some time but was not a close friend.

Gay's three-year-old son was home at the time his mother was killed, Mioduszewski said, but was unharmed.

After using his pickup truck to move Gay's body, the mallet and bloody towels, White returned to her trailer, the sheriff said. He said White took care of the boy in the morning, dressed him in his Halloween costume and took him to an area Meijer store to be picked up by his father.

A judge appointed a public defender to represent White, who is scheduled to return to court Nov. 8.

White told the judge that he was a church employee until Wednesday. White's church affiliation was not mentioned in court, but Christ Community Fellowship church elder Donna Houghton told WOOD-TV that White was a pastor at the church in Mount Pleasant.

White served prison terms for assault with intent to murder and for manslaughter and was released in 2007, the Michigan Department of Corrections told WLNS-TV.

The manslaughter conviction was for killing Vicky S. Wall in 1994 in Kalamazoo County, the Kalamazoo Gazette reported at the time.
