An argument between a dad and two homeless people on a beach in Malibu took an extremely violent turn over the weekend, ending with the father losing an eye. Deputies were told a man was with four family members when they were approached by two suspects, both believed to be homeless. The two homeless people confronted the dad, saying they were not allowed in the area, sparking an argument between the three people. One of the suspects, later identified as Richard Franck, whipped out a machete and began slashing the dad multiple times. The other four family members were chased by Franck and the other homeless person, LASD said.
