This was a simple rear-end crash. On June 30, 2021, J.D. rear-ended Dan Mleziva’s Tesla. J.D. was a lacrosse coach employed by one of the 6 private schools the defendants owned. He was driving home from a lacrosse event and thus was operating the vehicle in the scope of his employment with C.S., one of the defendants. Liability was admitted about a week before trial. The dispute and trial concerned the permanence of the client’s TBI, causation of his chronic headaches, cognitive and executive dysfunction, his lost earning capacity, and development and cause of hydrocephalus requiring brain surgery for a shunt.
