NEW CASTLE, Delaware (WPVI) -- Delaware State Police have arrested a woman accused of killing a pedestrian and injuring several other people during a double carjacking rampage on Sunday in New Castle.

The suspect has been identified as 30-year-old Brittallia Semaan, a resident of New Castle.

The incident started around 9:30 a.m. when police say Semaan carjacked the driver of a Chevrolet Trax on the 4000 block of New Castle Avenue (Rt. 9).

Police say a 67-year-old man, a 66-year-old woman and two juveniles were inside the vehicle at the time.

The 66-year-old woman sustained minor injuries after she was hit while Semaan was fleeing the scene, according to police.

Then, police say Semaan fled to the area of Rt. 9 and Boothhurst Boulevard where she struck and killed 47-year-old New Castle resident Joseph Stanavich, who was walking on the shoulder.

Troopers say Semaan was speeding at the time, and left her lane "for unknown reasons" and hit Stanavich.

Semaan is then accused of driving to the Brandywine Valley SPCA where police say she struck a 19-year-old woman in the parking lot. The victim sustained non-life-threatening injuries.

After fleeing that scene, police say Semaan struck a Maserati head-on while traveling on Rt. 141.

After the crash, a 62-year-old man driving in a Ford Explorer stopped to render aid but was subsequently carjacked by Semaan, according to police.
