GRAND JUNCTION, Colo. -- A Grand Junction man accused of trying to get his girlfriend to kill his ex-wife with the poisonous belladonna plant faces an attempted murder charge.

Stuart Shader, 34, was arrested Friday and remained jailed Wednesday in the Mesa County Jail on suspicion of menacing, third-degree assault, complicity to commit first-degree murder, criminal extortion, first-degree trespassing, false imprisonment, criminal mischief and a fugitive from justice warrant out of Moffatt County. His bond is set at $182,500.

According to an affidavit, Shader believed his ex-wife "was trying to ruin him" by taking him to court. In April, he allegedly asked his girlfriend if she could kill his former wife, the girlfriend told an investigator.

The affidavit said Shader wanted his girlfriend to sneak into his ex-wife's house and put the poisonous plant in a coffee ground can. His girlfriend said she practiced witchcraft and told Shader the plant would get the job done, according to the arrest affidavit.

Shader told his girlfriend he'd "understand" if she chose to kill herself or go to Mexico afterward, according to the affidavit.
