NODAWAY COUNTY —Law enforcement authorities have charge a northwest Missouri man with the murder of his father.

Just after 10:30 a.m. January 25, the Nodaway County 911 Center received a call requesting an ambulance for an 88-year-old man who was on the floor and unresponsive but breathing at 115 Oak Street in Burlington Junction, according to a media release from Sheriff Randy Strong.

The caller told the 911 operator he was the cause for his father being on the floor.

At the scene, deputies determined that this was an assault. The suspect was taken into custody. The victim was transported by ambulance to a local hospital where it was determined that his injuries were life threatening and he was transported to St. Luke’s Hospital.

The sheriff’s office applied for a search warrant for the home and conducted an investigation.

On Wednesday afternoon, the victim died. An autopsy was performed and it was determined that the man died as a result of trauma to the head, according to Strong.

On Thursday, prosecuting attorney Robert Rice amended the charges to Murder in the 2nd Degree. Lawrence Wayne Davison remains in the Nodaway County Jail.
