SAN ANTONIO, Texas (AP) _ Three men pleaded guilty to grave desecration charges for unearthing a corpse and placing a cigarette in its mouth and a beer on its chest.

Assistant District Attorney Scott Sullivan said Monday he will ask the judge to sentence the men to 10 years in prison, the maximum punishment.

Richard Campbell, 29, William F. ''Chip'' Mayfield, 22, and Ronald Lee Slavin, 21, entered the guilty pleas Monday to charges they desecrated the grave of Ludolph Tampke, who died in 1990 at age 84.

''I think they need counseling,'' said Cinda Steubing, who was married to Tampke's nephew.

Mayfield said the desecration was merely a drunken prank.

Authorities initially believed it was linked to a satanic cult. A deputy who visited the home of Mayfield and Slavin said the walls were covered with posters of the devil, satanic settings, swastikas and pornography.

''Even (though) myself and friends listen to cult music or are into satanic readings, we are in no way relating this grave digging experience to any cult practice,'' Mayfield said in a signed statement to deputies.
