"My family and I wanted to personally thank you," said Maurice Lea, the son of the victim.
The family wrote a letter to the sheriff's deputy that came to their aid.
"Currently, our society is quick to criticize law enforcement and neglect verbalizing our appreciation," said the victim, Lewis Lea. "I, too have been critical in my response."
"Your professionalism and concern made a difficult situation easier to handle," said son Lewis O. Lea.
Lewis Lea fell asleep in his car on May 17 waiting for his son's soccer practice to end. That is when someone came up and opened his car door. Lea jumped out, assuming something had gone wrong on the soccer field and they were coming to tell him.
"They crawled through the car and hit me directly in the back of the head," said Lea.
That knocked Lea to the ground. Four teens beat him up in the parking lot of the Washington Park Ecology Center.
