After Kim's birth, Dan completed his M.D. degree at Cornell in 1970. He then announced his intention to combine his medical expertise with a
J.D. degree and enrolled at
Harvard Law School. Betty was the main provider for the family while Dan attended
law school with the help of a student loan. After graduating in 1973, Dan was quickly hired by the largest law firm in
San Diego, California, which had a substantial defense litigation practice, and moved his family to the San Diego community of
La Jolla. Betty continued working part-time, often selling
Tupperware or
Avon products, while raising the children. In 1978, after five years of substantial defense litigation work and training as an associate, Dan left the large firm where he was well regarded. He then founded his own small boutique law firm, specializing in medical malpractice litigation on behalf of plaintiffs. Because of Dan's background as both an M.D. and trial attorney, the firm quickly enjoyed success. In the fall of 1982, Dan hired 21 year old
Dutch American Linda Kolkena (1961–1989), a former
Delta Air Lines flight attendant, Betty also believed that Dan used his legal influence to win sole custody of their children, sell their house against her wishes, and cheat her out of her rightful share of his income. The divorce was finalized in 1989, four years after Dan filed the petition. Betty Broderick's behavior became increasingly erratic. She left hundreds of profane messages on Dan's answering machine and ignored numerous
restraining orders that forbade her from setting foot on Dan's property. She vandalized his new home and even drove her car into his front door, despite the fact that their children were inside the house at the time. On April 22, 1989, Dan and Linda were married. Linda had been concerned about Betty's behavior and even urged Dan to wear a
bulletproof vest at their wedding. Dan refused to do so, although plain-clothes security was employed. However, Betty did not attend the wedding and it proceeded without incident. ==Murders==
