A grand jury Thursday handed down an additional assault charge for the man accused of killing one of his neighbors and seriously injuring another this past August.
Jake Gastler, 22, is now charged with one count of second-degree murder and two counts of first-degree assault in the death of 30-year-old Zachary O'Connor and the assault of O'Connor's father, 57-year-old Michael.
The Callaway County Sheriff's Office said Gastler originally called authorities to report that he had found the men lying in a pool of blood in a home on the 1000 block of Blue Ridge Road.
Zachary O'Connor was pronounced dead at the scene and Michael was airlifted to University Hospital in critical condition.
Gastler was arrested after inconsistencies in his story and later admitted that he had assaulted the two men after an altercation.
He is scheduled to be arraigned on February 24.
