Man Arrested In Connection With Mother's Death in Boulder County

BOULDER COUNTY, CO — A man was arrested Tuesday in connection with his mother's death in a home north of Boulder, authorities said.

Jeffrey Apprill, 55, was charged with tampering with a deceased human body, criminal exploitation of an at-risk person, at-risk negligence resulting in serious bodily injury, caretaker neglect and concealing a death, the Boulder County Sheriff's Office said.

Deputies were called to check on 78-year-old Karen Apprill in the 3900 block of Bosque Court on Aug. 28, 2020. The deputies were told that her son was in the hospital and that she hadn't been heard from in more than a week.

Deputies found the mother's body decomposing inside the home, and later learned that she had died between 7 and 10 months prior to the discovery, according to the sheriff's office.
