DNA from a relative of a suspect led investigators to David Allen Snyder, a former Key West resident whose DNA matched evidence from the crime scene. Though Snyder died in 2008, his identification brings long-awaited closure to the Jenkins family—and marks the 66th time genetic genealogy has cracked a Florida cold case.
