A California Highway Patrol officer clocked a black 2015 Mercedes C63 AMG sedan accelerating to roughly 85 mph on the south shoulder of US-50 west of Echo Summit at around 5:25 a.m. on August 4, and by the time the chase ended miles later, the car was wrapped around a boulder on a South Lake Tahoe side street, three people were injured, and all three were under arrest.
A second officer stationed at a curve known locally as Gunmount clocked the fleeing sedan crossing double yellow lines at 70 mph on RADAR before officers activated their lights and sirens, according to CBS News. The driver illegally passed other cars during the pursuit as officers followed the Mercedes off Highway 50 and onto Highway 89, the outlet reported. Gunmount takes its name from a nearby avalanche control gun tower near Echo Summit, a mountain pass that tops 7,300 feet as it links the Sacramento region to the Tahoe Basin.
Officers Lost Sight of the Car Before the Crash
Authorities lost sight of the Mercedes along Highway 89, and pursuing units deactivated their emergency lights and sirens after losing visual contact, according to CHP South Lake Tahoe. Officers kept driving south and eventually found the car crashed and immobilized on a boulder at Portal Drive, a residential street in the River Park Estates neighborhood off Highway 89 near South Upper Truckee Road. The driver and two passengers were injured in the crash, though officials have not released their identities or conditions, per CBS News.
All three ran from the crash scene before CHP officers caught up with them and made arrests, the station reported. Both passengers had active felony no-bail warrants out for their arrest before the chase even began, according to CBS News — a detail that offers a possible explanation for why the group tried to outrun officers at high speed through a mountain corridor rather than pull over.
Felony Charges Stack Up Despite Clean Record
The driver had no prior criminal record before the incident, but now faces a stack of felony charges including felony evading, felony hit-and-run causing injury, reckless driving causing injury, and resisting arrest, per the CHP South Lake Tahoe account. Under California Vehicle Code Section 2800.2, felony reckless evading applies when a driver flees law enforcement with willful or wanton disregard for safety — including racking up three or more point-assigned traffic violations during a chase — and it carries penalties of up to three years in state prison and $10,000 in fines, according to Shouse Law Group.
The felony hit-and-run charge stems from California Vehicle Code Section 20001, which makes it a felony to flee the scene of a crash that injures another person, regardless of whether that crash involved another vehicle or a fixed obstacle like a boulder, per the Los Angeles Criminal Lawyer firm's explainer on the statute. That means injuries to the driver's own passengers can trigger the charge, since drivers involved in injury crashes have a legal duty to stop, render aid, and identify themselves. Combined, the felony hit-and-run and evading counts carry far steeper penalties than a standard traffic violation.
Echo Summit Has Seen This Before
This wasn't the first time this year that Echo Summit served as the backdrop for a high-speed escape attempt. Five months earlier, in March, CHP officers ended a separate chase along the same corridor by deploying spike strips near Gunmount to stop a suspect who had led police on an 80-mile pursuit from Rancho Cordova to Meyers, according to the Placerville NewsWire. The recurring pattern underscores how the mountain pass functions as a natural funnel for drivers trying to slip from the Sacramento Valley into the Tahoe Basin.
Statewide, pursuits like this one are common and frequently dangerous. In an annual report submitted to the state legislature, the California Highway Patrol documented 11,985 police pursuits across California in a single year, with 19% ending in a crash and more than 35% of those crashes resulting in injuries. Portal Drive itself sits near the Upper Truckee River and connects to trailhead parking for popular South Shore mountain biking and hiking routes, meaning a chase that spills off the highway there carries risk for residents and recreational users alike, according to Trailforks.
Separately, statewide vehicle theft numbers have been trending downward. California Highway Patrol data published in July showed vehicle thefts across the state dropped more than 24% in 2025 compared to 2024, while law enforcement recovered 84% of stolen vehicles statewide — the largest single-year decline in California vehicle thefts in more than five years. No charges related to auto theft have been reported in connection with this Mercedes, and the vehicle's ownership status was not detailed in available reporting.
