Ten years after the brutal murder of 10-year-old Victoria Martens in Albuquerque, New Mexico, authorities confirm that a fourth suspect remains unidentified and at large. The case, which shocked the nation, involved the death of Victoria on August 23, 2016, in a Westside apartment. While three individuals have been convicted and sentenced for their roles in the crime, a male intruder whose DNA was found on the victim’s body has never been identified. The suspect is referred to in court documents as John Doe. Victoria’s mother, Michelle Martens, and her boyfriend, Fabian Gonzales, along with Gonzales’ cousin, Jessica Kelley, were initially charged but later faced reduced convictions or were released after prosecutors determined they were not present during the actual killing. Kelley testified that an unknown man entered the apartment, strangled Victoria, and fled. Despite extensive investigations, including DNA analysis that could not match the profile to any known individual in national databases, the unidentified male remains free. Albuquerque Police and the Bernalillo County District Attorney’s office continue to accept tips regarding this fourth suspect. The case remains open, with prosecutors expressing hope that renewed public interest and advancements in forensic technology may eventually lead to an identification. The family of Victoria Martens continues to seek justice, with a civil lawsuit against the city of Albuquerque pending trial. The investigation highlights significant challenges in solving cold cases where initial evidence was compromised or where suspects remain unknown. Authorities urge anyone with information regarding the unidentified male to contact the Albuquerque Police Department or the District Attorney’s office. The case serves as a grim reminder of the complexities involved in violent crimes involving drug-fueled chaos and the enduring impact on victims' families. As the tenth anniversary of the tragedy approaches, the community remembers Victoria through memorials and vigils, while law enforcement maintains that the search for the fourth suspect is ongoing and active.
