TEMPLE HILLS, Md. — The Prince George’s County Police Department’s Collision Analysis and Reconstruction Unit is investigating a fatal crash that killed 28-year-old Christopher Umanzor of Waldorf on March 27, 2026. Officers responded to the 4300 block of Branch Avenue around 9:10 p.m. for a two-vehicle collision. Umanzor died at the scene from injuries sustained in the crash while the driver and passenger of the second vehicle escaped without injury.
Preliminary findings show that Umanzor’s vehicle struck the rear of the second car for reasons still under review. Both vehicles then veered off the roadway and Umanzor’s car hit a guardrail. The Collision Analysis and Reconstruction Unit continues to examine all factors including vehicle speeds, road conditions and any contributing circumstances. No charges have been filed at this stage as the investigation remains active.
The incident occurred on Branch Avenue, a heavily traveled corridor that serves as a vital link between Prince George’s County and Southern Maryland communities including Waldorf in Charles County. Many residents from Charles, St. Mary’s and Calvert counties use this route daily for commuting to work, family visits and errands in the Washington area. The loss of a young Waldorf man has brought the tragedy close to home for Southern Maryland families who share these roads.
Umanzor’s death underscores the unpredictable nature of traffic incidents on busy arteries like Branch Avenue where rear-end collisions can escalate quickly when vehicles leave the paved surface. The Prince George’s County Police Department has not released additional details about the vehicles involved or the exact sequence beyond the initial rear-end contact and guardrail impact. Investigators are working to reconstruct the moments leading up to the crash using physical evidence, witness statements and any available video or camera footage from the area.
Southern Maryland drivers know Branch Avenue well as it runs through Temple Hills and connects directly to major routes heading south into Charles County. Local commuters often travel this stretch during evening hours when visibility and traffic flow can change rapidly. While the specific cause here remains undetermined, the case highlights the ongoing need for alertness on shared roadways that carry thousands of vehicles each day between the metropolitan area and the Southern Maryland peninsula.

The Prince George’s County Police Department routinely relies on community assistance in collision reconstructions to determine contributing factors and ensure accurate findings. In cases like this where one driver has died at the scene, every detail from nearby drivers, pedestrians or business owners can prove valuable. Southern Maryland residents who frequently use Branch Avenue or were in the Temple Hills area on the evening of March 27 are encouraged to review their memories or dash-cam footage and reach out if anything seems relevant.
The Collision Analysis and Reconstruction Unit specializes in detailed examinations that can take days or weeks depending on the complexity. Their work helps determine whether mechanical issues, environmental conditions or human factors played a role. While the investigation continues authorities have not indicated any immediate road closures or changes to traffic patterns in the 4300 block of Branch Avenue beyond standard safety measures already in place.
The Prince George’s County Police Department asks the public to remain patient as the reconstruction progresses. Updates will be released when additional verified information becomes available.
