June 7, 2025

Delaware State Police are investigating a fatal two-vehicle crash that occurred June 6 in Milton.

About 4:32 p.m., a Ford Bronco was traveling northbound on Mulberry Street approaching Route 16. At the same time, a fully marked Sussex County EMS Chevrolet Suburban that was responding to an emergency call with its emergency equipment activated was traveling westbound on Route 16 approaching Mulberry Street.

The preliminary investigation revealed the Bronco proceeded past the posted stop sign at Mulberry Street and into the path of the responding EMS Suburban. As a result, the front of the Suburban hit the passenger’s side of the Bronco. After the collision, the Bronco struck a tree.

The driver of the Bronco, Mary O’Bier, 74, of Ellendale was taken to an area hospital where she later died.

The driver of the Suburban, a 38-year-old female Sussex County paramedic, was taken to an area hospital with non-life-threatening injuries.

The roadway was closed for approximately three hours while the scene was investigated and cleared.
