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 that led to a series of crashes on Sunday.

The incident started around 9:30 am when police say 30-year-old Brittallia Semaan carjacked the driver of a Chevrolet Trax on the 4000 block of New Castle Ave (Rt. 9).

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

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

The suspect then fled to the area of ​​Rt. 9 and Boothhurst Blvd. where she struck and killed a 48-year-old New Castle County man. He was not been identified.

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.

A 34-year-old man and a 26-year-old woman in the Maserati were not seriously injured.

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.

“He confronted her and she was told to exit his vehicle. As she did, she entered the driver’s side and began fleeing the scene with a 77-year-old female in the front seat passenger’s seat still inside,” said Master Corporal Heather Pepper with the Delaware State Police.

With the female victim still in the car, Semaan then fled to the area of ​​Hamburg Road where police say she crashed into a Honda Odyssey.

The 52-year-old woman in the Honda Odyssey and the 77-year-old female in the Ford Explorer were not seriously injured.

Police say an off-duty police officer and a former law enforcement officer, who witnessed part of the incident, apprehended the suspect at the final crash scene until troopers arrived and she was taken into custody.

Anyone who captured video of any of these incidents or has further information is asked to contact Delaware State Police.
