Rick Roberts, 49, a former demolition derby champion and owner of an auto shop in Sonora, California, was found dead inside his shop on February 16, 2014. A friend discovered his body and called authorities. An autopsy determined Roberts had been shot twice: one bullet grazed his shoulder and a second penetrated his chest and was fatal. Investigators reported no signs of forced entry or a struggle, a detail that suggested Roberts likely knew his attacker.

The investigation initially produced few leads but later focused on an extramarital relationship Roberts had with 46-year-old Cheryl Lynn Lucero of Sonora. According to reports, Lucero was questioned, confessed to planning and carrying out the killing because Roberts would not leave his wife, and was arrested and incarcerated for his murder. The case underscores the lethal consequences of obsession and left a lasting impact on Roberts’ family and the community.

Did anyone in Sonora know Roberts’ routines or have information that wasn’t reported at the time?
