West Sacramento police are asking the public for help solving the death of Dennis Tapp, a 46-year-old unhoused man who was found with significant injuries along railroad tracks behind 975 F St. early on November 23, 2024, and died later that day. Nearly two years have passed with no arrest, and investigators are once again asking anyone with information to come forward.
According to the Sacramento Bee, police officers found Tapp that morning at the encampment behind the F Street address, and he was taken to UC Davis Medical Center in Sacramento, where he died. In a Facebook public appeal posted Thursday, the West Sacramento Police Department specified that the assault happened at approximately 7:40 a.m. at an unhoused encampment along the railroad tracks behind 975 F St., adding new timing detail to a case that has otherwise stayed quiet for nearly two years. Anyone with information is asked to call the department's investigations unit at 916-617-5056 or share the department's Facebook post to help it reach more potential witnesses.
A Trauma Center Built for the Region's Worst Injuries
Tapp's transport across the river to UC Davis Medical Center reflects the severity of his injuries. The hospital operates as inland Northern California's only Level 1 adult and pediatric trauma center, according to UC Davis Health, a designation that makes it the region's default destination for the most critical trauma cases across dozens of counties.
The location behind 975 F St. sits near an Extra Space Storage facility close to the corner of F Street and Jefferson Boulevard, adjacent to active rail lines, per the facility's own site listing. It is the kind of trackside corridor that has drawn unhoused residents to camp nearby, and it is not the only spot in West Sacramento where that proximity to rail infrastructure has turned deadly.
A Pattern of Danger Along the Rail Corridor
In October 2024, just weeks before Tapp's death, a responding fire truck drove over a concealed carpet near rail tracks along the 500 block of Jefferson Boulevard, killing an unhoused man and injuring an unhoused woman, Hoodline reported at the time. That incident prompted death investigations by police and the California Highway Patrol, underscoring how the same rail corridors that shelter unhoused residents have repeatedly produced fatal outcomes.
The risks are compounded by the sheer scale of homelessness concentrated in West Sacramento. The 2026 Yolo County Point-in-Time Homeless Count, conducted in January, found West Sacramento had the highest unhoused population of any city in the county, with 358 individuals counted out of a countywide total of 912, according to the Yolo County Health & Human Services Agency. Back in 2024, the year Tapp died, the county's homeless count had already recorded 289 individuals in West Sacramento, a rate of 53.2 unhoused people per 10,000 residents that was well above the countywide average at the time, per the Yolo County Homeless and Poverty Action Coalition.
Most of the County's Homeless Population Remains Unsheltered
The county's most recent data shows that 65% of all homeless individuals across Yolo County, 597 of 912 people, were unsheltered, living in encampments, vehicles, or rail corridors rather than shelters, the same Yolo County Health & Human Services Agency report found. That unsheltered reality leaves people like Tapp exposed to violence with little protection, even as broader crime trends in the region have moved in the opposite direction.
Statewide, California recorded its lowest overall homicide rate since data collection began in 1966, according to figures released by the California Department of Justice in July. Closer to home, Sacramento County's sheriff's office reported 18 homicides in 2025 outside city limits, the county's lowest annual total in 55 years, while the city of Sacramento recorded 42 homicides that year, per CBS News Sacramento. Tapp's unsolved case stands as a reminder that even as overall violence declines, homicides involving unsheltered victims can remain especially difficult to close.
Under California Penal Code Section 187, murder is defined as the unlawful killing of a human being with malice aforethought, and a first-degree murder conviction carries a penalty of 25 years to life in state prison, according to the California Legislative Information database. No arrests have been announced in Tapp's death, and it remains unclear what, if any, new forensic leads or witness accounts have emerged since November 2024 to prompt this week's renewed appeal. West Sacramento police continue to ask anyone with information to contact the investigations unit.
