More information has been obtained regarding an attempted murder charge being filed in Cooper County.

According to a Boonville Police report, at approximately 8:53 p.m. on January 3, officers were dispatched to the 1300 block of Main Street for the report of shots fired. Dispatch reported shortly after, the firearm was taken from the suspect, later identified as 27-year-old Kalynn Dean Hendren.

Upon arrival, contact was made with an alleged victim, who stated Hendren pointed a rifle at her, approximately three inches from her face, and stated “I’ll kill you, I’ll kill you. I’m going to kill everybody in this house.”

The woman said she grabbed the barrel of the rifle, and Hendren started fighting over getting control of it. At one point, the woman said she believed she was on her knees and had just gotten the barrel away from her head when Hendren said again “I’m going to kill you” and fired one round from the rifle. The woman said she had hold of the barrel again, and Hendren manipulated the action of the rifle and chambered another round.

Officers found the spent shell casing, and the bullet fragment was found behind a framed picture hanging on the wall of the living room.

According to court documents, Hendren is charged with Class B Felonies for Attempted Murder in the Second Degree and Domestic Assault in the First Degree; and an Unclassified Felony for Armed Criminal Action. Bond is set at $500,000 cash or surety.

Hendren entered a plea of not guilty during his arraignment hearing on Wednesday, January 6. A counsel-status hearing is scheduled to be held at 10:30 a.m. on Tuesday, January 12, at Cooper County Circuit Court.
