Investigators say foul play may be involved after remains were discovered in East San Jose.
SAN JOSE, Calif. — San Jose police are investigating whether a severely decomposed body found inside a pickup truck in East San Jose is tied to the disappearance of a 40-year-old local man whose vehicle was recovered at the scene.
The case moved into wider public view Tuesday after detectives asked for help identifying the dead person and tracing the final movements of Aldama Refugio Jr., the truck’s registered owner, who remains listed as missing. The discovery came 10 days earlier, but authorities said the condition of the remains has slowed identification and left key questions unanswered about how long the body was in the vehicle and what happened before the truck was found.
According to police, officers were called at about 6:56 a.m. on March 21 to the area of Francis Drive and McKee Road after a report of suspicious circumstances. When they arrived, they found a severely decomposed body inside a red two-door 2010 Nissan Frontier. The Santa Clara County Office of the Medical Examiner responded and took custody of the remains. By Tuesday, detectives had publicly connected the truck to Refugio, a San Jose resident who police said was last seen in early 2026. In announcing the appeal for information, investigators said they believe foul play may be involved. The department did not say who first spotted the vehicle, whether it appeared abandoned, or whether any signs of trauma were visible when officers opened the truck.
Police have released a photo of Refugio and an image of the Nissan in an effort to build a timeline from the public. Detectives are asking whether anyone saw Refugio, the pickup, or activity around the truck before March 21. What remains unknown is central to the case. Authorities have not said where Refugio was last definitively seen, whether the remains are believed to be those of Refugio, or whether any evidence inside or around the truck points to a suspect. They also have not said whether the vehicle had been parked in that area for days or weeks. Because the body was in an advanced state of decomposition, the medical examiner’s office is expected to play a major role in determining identity and cause of death. Until that happens, police are treating Refugio as a missing person while also pursuing the case as a death investigation.
The location adds to the urgency for detectives. Francis Drive and McKee Road sit in a busy section of East San Jose near homes, shopping areas and regular commuter traffic, which raises the possibility that someone may have seen the truck without realizing its significance. In cases involving remains found inside vehicles, investigators often rely on neighborhood sightings, store surveillance, license plate readers and phone records to reconstruct the last known timeline. Police have not said what evidence they have already collected, but the release suggests they are still trying to answer basic questions about movement, timing and contact. The case number, 26-085-9707, indicates the department has formally opened and classified the matter as a death investigation rather than only a missing-person inquiry.
The next steps are likely to come from forensic work and follow-up interviews. The medical examiner must confirm the identity of the decedent and determine, if possible, the manner and cause of death. Detectives, meanwhile, are expected to compare witness accounts with any digital or video evidence tied to the truck’s route and final location. No arrest has been announced, and no charges have been filed. Police also have not scheduled a public briefing beyond the written appeal for assistance. Any major shift in the case will likely come when the remains are identified, when investigators establish when Refugio was last seen, or when evidence shows who had control of the truck before it was found on March 21.
For now, the public picture remains narrow but grim: a missing man, a recovered pickup and a body still without a confirmed name. The short police statement left many details unstated, yet it pointed clearly to the seriousness of the inquiry. By naming Refugio and releasing the truck description, detectives signaled that public memory may be as important as laboratory work in the days ahead. A passerby may remember the red pickup parked out of place. A neighbor may recall when it first appeared. Someone may know when Refugio last drove it. Those small pieces often become the frame for a much larger answer when investigators are working backward from a scene that has already gone cold.
The case remained open Tuesday, with San Jose police waiting on forensic identification and seeking new leads about Refugio and the red Nissan. The next major milestone is expected to come when the medical examiner confirms the decedent’s identity and detectives update the public on where the investigation stands.
