Authorities say DCI, along with an Iowa State Patrol Tactical Team, and Carroll County Sheriff’s Deputies, executed a search and arrest warrant for 53 year-old Thomas Henderson, of Lake City. Based on investigative findings, sufficient probable cause was developed to file charges. Henderson was arrested and taken into custody without incident at an apartment building in Lake City. He’s currently being held in the Carroll County Jail.

Henderson is charged with two counts of first degree murder in connection with the deaths of 48-year old Tammie Lee Devore, and her son, 30-year old Karl Allen Devore, both of Glidden. On Sunday, May 18th, 2014, the Carroll County Sheriff’s Office received a 911 of an unconscious individual at 129 Carroll Street, Lot #5 in Glidden.  Upon arrival and through further investigation, law enforcement officials discovered Tammie Devore and Karl Devore deceased at the residence.

The investigation continues into this case. The Calhoun County Sheriff’s Office and the Lake City Police Department assisted with the investigation.
