El Cajon police are actively using innovative phenotyping technology to investigate a 26-year-old cold case murder, providing a potential breakthrough in a long-unsolved mystery. The victim, referred to as Jane Doe, was discovered in August 1998 with a crushed skull in a field, and despite extensive efforts, her identity has remained elusive. Retired officers Fran Deck and Kevin Trotter have stepped in as cold case investigative volunteers, driven by their desire to see justice served. They believe that the new composite likeness created by Parabon, a phenotyping company, could help the community recognize the victim and lead to vital information. The case is particularly challenging due to the scarcity of leads, but a t-shirt found with the victim has been a focal point in their investigation.

Deck and Trotter's commitment reflects the emotional weight of unresolved cases that linger long after retirement. This renewed investigation highlights the importance of technological advancements in solving cold cases, offering hope to families seeking closure. The El Cajon community is encouraged to assist in the investigation by sharing any information they might have.
