After a year-long legal battle, a trial will soon come to fruition for the Gilroy woman who allegedly killed her husband and daughter in a drunken car crash in Los Gatos last February. 

Fifty-two-year-old Stacy Lonnberg, who is charged with two counts of murder and one count child endangerment, will go before a jury on May 20 at 8:30 a.m. in San Jose. 

Despite claims of mental incompetence from her defense lawyer that stalled criminal proceedings for several months, Lonnberg was deemed mentally capable of withstanding trial on Nov. 28. 

Lonnberg’s husband Fred Lonnberg, 57, and her daughter Tiffiny Gillette, 26, died when Stacy was driving under the influence and rolled the family’s pickup truck on Highway 85 in Los Gatos on Jan. 14, 2012, according to the California Highway Patrol. Lonnberg’s blood-alcohol content measured twice the legal limit at 0.16.

Tiffiny was pronounced dead the scene, and Lonnberg’s husband was pronounced dead hours later at Valley Medical Center. Lonnberg’s grandson was unharmed. 

Originally charged with manslaughter, the Santa Clara County District Attorney’s office upped Lonnberg’s charges to murder 10 days after the car crash. If convicted, Lonnberg could face a minimum of 15 years in prison.
