Daniel Edward Sullivan, 42, was found murdered in his Redding, California, home on Lema Road on February 18, 1994, alongside 22-year-old Maria Celeste Mayon. Both victims had been brutally killed. The Redding Police Department conducted numerous interviews after the discovery, but the investigation went cold when leads dried up and no suspects were identified. There were no photographs of the victims released to assist public appeals, which limited outreach efforts.

Investigators have periodically tried to reignite interest in the case and as of 2020 remained open to new information, hoping even a minor tip could help solve the murders. The unresolved nature of the killings continues to trouble the families and the community. If anyone remembers details about that night or the victims, please come forward with information.
