Joseph Aguayo, a career criminal with a long record, kidnapped and strangled 29-year-old Eva Chu in Sacramento in 1979. Chu, who was 7 months pregnant, had left her job in downtown Sacramento, enroute to a doctor’s appointment, when she disappeared. Her body was found 4 days later by a creek bed. Aguayo had a history of violence, including a home invasion robbery, kidnapping, and attempted murder. In that case, he beat his girlfriend, then left her locked in the trunk of her car to die.
Aguayo was identified as Eva’s killer in 2002 through a DNA match. He was convicted of killing Chu and her unborn baby in 2006, and sentenced to death.
