Teen accused of poisoning his grandmother's coffee

KIRKSVILLE — A north-central Missouri teenager is accused of trying to poison his grandmother about two weeks before she died in a car crash.

Adair County Circuit Court documents show 18-year-old Robert William Sapp of Gibbs was arrested Friday and charged with attempted murder. He was accused of putting antifungal spray into the coffee of his grandmother, 74-year-old Wilma Kelsey.

Kelsey had filed a complaint with the sheriff's department in early September. On Sept. 17, Kelsey died when the car she was driving on U.S. 63 crossed the median and hit a truck head-on.

According to court documents, Sapp told police he wanted his grandparents "dead because they were rude and were always telling him what to do."

Sapp was being held on $100,000 cash bond. Lab results of the coffee and an autopsy on Kelsey are pending.
