Case Summary

On August 28, 2020, Boulder County Sheriff’s Office deputies were dispatched to check the welfare of 78-year-old Karen Apprill who had reportedly not been heard from for more than a week and her son and caregiver, Jeffrey Apprill, had been admitted to a local hospital. Deputies determined Karen lived in a home in the 3900 block of Bosque Court in unincorporated Boulder County.

Deputies responded to the home and after knocking on the door, calling phone numbers associated with the home, and speaking with friends and neighbors entered the home to check on Karen. Deputies discovered a decomposing body inside of the home. Detectives obtained a search warrant for the home and based upon initial observations it was believed the individual, later identified as Karen Apprill, had died seven to ten months prior to the discovery.

During the autopsy, Karen’s body was described as being in the advanced stages of decomposition and both antemortem and postmortem trauma was discovered. Karen’s cause of death was listed as undetermined and the mechanism of death could not be determined.

In the following months detectives worked with Boulder County Adult Protective Services and served multiple search warrants. Based on statements and physical evidence investigators are not able to determine the cause and manner of Karen’s death however they were able to establish probable cause to arrest Jeffrey Apprill for the above listed charges.
