On the night of December 26, 2017, Alfred Wilhelm, 53, was shot and killed behind a central-valley swap meet in Las Vegas in the same violent encounter that also took the life of 27-year-old Rhonda Ballow. Nevada sex offender registry records show Wilhelm had a prior conviction for first-degree rape in Hawaii in 1984. Court documents say the killings were motivated by a personal vendetta against sex offenders.

Investigators focused on 32-year-old Michael Thompson after he allegedly confessed to a neighbor, saying he shot Wilhelm because Wilhelm was a sex offender and killed Ballow when she refused to leave. Witnesses also described seeing a man matching Thompson’s description shoot Wilhelm; one witness fled after the first shots and returned about 45 minutes later to find Ballow wounded and asking for help. Police interviewed Thompson on January 5, 2018, after a witness spotted him; he denied information and refused a DNA sample. Authorities arrested Thompson in January 2018 and charged him with two counts of murder.

Are there any readers who were in that swap meet area on December 26, 2017, or who might have information about what was seen that night?
