According to the police report, which was obtained from Channel 4, Dwayne Johnson [Johnson's 17-year-old son] saw the argument as it escalated to the
point that Dennis Johnson grabbed his wife in a choking manner with his left hand and held a knife in front of her face. According to the report, Donna Johnson yelled, "What are you going to do, kill me? Go ahead." Dennis Johnson replied, "You don't think anybody will hit you?"
After a few moments, Johnson let his wife go but was still yelling and
holding the knife, the report said. When Dwayne attempted to stop the
argument, his father said, "Don't you even, or I'll knock you the
[expletive] out." Donna Johnson replied, "No you won't. You won't touch him." Dwayne Johnson told police he believed his father would hit him, so he ran to a neighbor's house and asked her to call
911. He then returned to the house, saw the argument had died down, and called 911 himself.
