A summary of Southern California-related business litigation developments during the week of March 26:

Parents Blame Son’s Murder on Bank: Wells Fargo Bank was sued in Los Angeles Superior Court Wednesday by an Oregon couple, Frank and Susan Chase, who contend that their son, Mathew Marshall Chase, was kidnaped and fatally shot because of poor security and negligence. In June, 1988, 22-year-old Chase disappeared after he went to a Wells Fargo branch in Los Angeles to make a deposit at an automated teller machine. His body was found in March, 1989. The suit says Chase was abducted after the machine mistakenly indicated that he had insufficient funds to withdraw cash, presumably angering his assailants. (Filed March 28, Case No. C756791)
