Janelle Cruz

Janelle Cruz was a young woman whose murder remained entangled for years with suspicion focused on the people around her. The eventual DNA profile of her killer matched the profile from three other murders, overturning the early emphasis on her personal circle and making her case a crucial link in a wider investigation.

Identity and Last Known Hours

On the night Janelle was killed, a neighbor heard her Chevette, recognizable by its loud muffler, arrive at about 11:15 p.m. The neighbor heard the engine stop and a door slam. Earlier, a co-worker had left the residence about half an hour before Janelle returned. At 4:00 and 5:30 the next morning, two different neighbors noticed an unusually large amount of light coming from the home. These observations marked the last known movements around the residence, but did not by themselves explain what had happened inside.

Janelle’s sister, Michelle, was away on vacation when she received the news of the murder. The telephone connection was unclear enough that Michelle initially misunderstood the message as saying Janelle had married. The episode conveys the distance and disbelief through which the news reached her family, before the words were repeated more clearly.

The Circle Under Suspicion

Lead investigator Larry Montgomery and his colleagues examined Janelle’s recent activities and found several young men connected to her life. Randy Gill, whom she had met at YMCA camp, had been involved with her and called on the night she was killed; she had ended their relationship two weeks earlier. Martin Gomez, an ex-convict she had met at a former workplace, had entered a relationship with her that she broke off after he became obsessive and controlling. Philip Michaels, a lifeguard she had only recently begun dating, had spent the day with her before the murder.

Other men also drew attention. David Decker, whom Janelle had met when he was a counselor at YMCA camp and she was a camper, had last seen her two days before her death. David Thompson, a co-worker at Bullwinkle’s, was a different person from Ron Thomsen, the last boy known to have seen her alive. Dave Kowalski, another boyfriend, visited Janelle at home on the day she died, told her he loved her, and gave her a Seiko wristwatch. The watch was found beside her body, turning an ordinary token of affection into an object investigators had to consider in the case.

The inquiry also included people less clearly connected to her. Bruce Wendt, described as an oddball, had been to Janelle’s home shortly before the murder. A hostile handwritten description beside his name in her address book indicated that she had regarded him with strong dislike. The growing list of acquaintances and visitors gave investigators many possible avenues, but also kept attention fixed on the assumption that the killer belonged to Janelle’s immediate orbit.

Suspects Ruled Out and the DNA Link

Investigators collected blood from Mike Martinez, whose name appeared among Janelle’s associates. In early July, laboratory results eliminated him as a suspect; the co-worker under scrutiny was eliminated as well. DNA profiling had not yet entered forensic practice, but serology offered a partial biological description of the killer. He was a nonsecretor, a trait found in about 20 percent of the population, and had an unusual PGM type. The combination was estimated by a forensic scientist at the Orange County Crime Lab to occur in approximately one percent of the population.

Even with those results, investigators believed the answer lay among the young men in Janelle’s immediate circle. About ten years later, development of the killer’s DNA profile conclusively excluded Martinez and the other boyfriends and male friends who had initially been scrutinized. Instead, the profile matched an unidentified killer responsible for three other murders. The forensic connection changed the meaning of the earlier investigation: the many personal leads had not identified the killer, while evidence preserved from the cases ultimately revealed a pattern beyond Janelle’s social world.

Significance in the Investigation

Janelle’s case shows how a plausible investigative focus can become a constraint. Her relationships and recent visitors supplied names, histories, and objects to examine, but none of those early suspects matched the killer’s DNA. The eventual match joined her murder to three other killings and helped establish that the person responsible was not one of the men investigators had initially treated as the likely answer.

The shift was also a change in the kind of knowledge the case could offer. Early inquiry depended on reconstructing Janelle’s contacts and interpreting their connections to her; later forensic comparison could test those suspicions against biological evidence. Her murder thus became significant not only as a crime against an individual, but as a case whose DNA profile helped disclose a broader series.
