If you have issues with your neighbor, take them up with your neighbor (and do it in a civilized way!) Leave the lawn guy alone! Unfortunately it did not go down that way, as reported at mysuncoast.com (WWSB):
According to the Charlotte County Sheriff’s Office, deputies met with the victim, the owner of a lawn service business, at a residence in the 6400 block of Thorman Road around 4 p.m. Wednesday.
The victim told deputies he was hired to mow the lawn at the residence and was in the process of doing so, when 71-year-old Patrick Botelho approached him.
