Roger Dale Madison was 15 when he left his Sylmar, California, home on his motorcycle after an argument with his father about smoking on December 16, 1968, and never returned. At first his disappearance was treated as a possible runaway case.

In 1970 Mack Ray Edwards, who lived near the Madison family and was known to Roger, confessed to murdering Roger. Edwards said he lured Roger to an orange grove, stabbed him to death, and buried him under the Route 23 Freeway while it was under construction, using a bulldozer from the site. Edwards led investigators to the location but Roger’s remains were not recovered. Edwards, already convicted in other child murders, died by suicide in prison in 1971 before he could be tried for Roger’s killing.

A renewed search under the freeway in 2008 was unsuccessful and the case remains unsolved, though authorities believe Edwards was responsible. Does anyone have information about Roger’s last movements or memories of the area in 1968 that could help locate him?
