A Gallup man has confessed to police that he tried to kill a nun with poison two years ago because he wanted more attention from a priest.

Derek Kolb told officers he tried to kill 81-year-old Sister Mary Margret two years ago because he wanted her out of the way. The 19 year old said he felt he was competing with the nun for the attention of Father Tom Maikowski.

Kolb confessed that he laced cereal with toxic acid and mixed the nun’s tuna with window cleaner. Sister Mary Margret was not seriously injured.

According to a police document, Kolb told police that he was gay and he “sometimes questioned if he was as important to Father Tom and Sister Mary was.”
