Missing since July 14, 1988 from Potomac, Montgomery County, Maryland.
Circumstances of Disappearance
Lisa Tu was last seen in Potomac on July 14, 1988. Her husband, Gregory Tu, was sentenced to 30 years in prison for her homicide in 1992.
The prosecution argued that Gregory Tu was troubled by an affair his wife was having and heavily in debt because of business problems and gambling debts. He withdrew $44,000 from the college fund of his wife's son without her permission, prosecutors said, and then shot his wife of 10 years as she lay on the sofa in their Potomac home.
Two days later he paid a garbage collector to dispose of the sofa. In his car police found a meat cleaver, a knife, twine and plastic. A spot of blood was found on the dashboard. Additional droplets of blood, some of which matched Lisa Tu's, were found in parts of the basement, according to prosecution witnesses.
The defense contended that Tu put his wife on a plane to San Francisco on July 14, 1988, the day after police say she was murdered. When her family did not hear from her for days, then weeks, they found she had never arrived in San Francisco. Lisa's body has never been found
