Lake County, Florida - Kolby Parker is accused of stabbing his 77-year-old grandfather Ronald Wells to death on Saturday night.

The two had an argument while smoking marijuana, and the 77-year-old allegedly attacked Parker with a knife.

During the conversation with police, the man allegedly pulled out two human ears from his pants pocket, which apparently belonged to his grandfather. He then attacked one of the officers and tried to grab his gun, but was unsuccessful. He was taken into temporary custody.
