BIRMINGHAM, Alabama - The driver of a MAX DART bus that struck and killed a special needs woman in Birmingham's Southside was at fault in the accident, police said Monday.

The driver, 51-year-old Alex James Mixon, failed to yield the right of way to Pouneh Bahri, who was in the crosswalk, said Birmingham police spokesman Lt. Sean Edwards. The March 4 accident killed the 25-year-old woman while she was walking home after class.

Mixon was traveling eastbound on 14th Avenue when he turned left onto 20th Street. Bhari was struck in the crosswalk. Witnesses said she was dragged about a half block before the DART bus came to a stop. She was pronounced dead a short time later.

Birmingham police spokesman Lt. Sean Edwards today released these findings from the investigation:

The findings were based on numerous witness statements who all had different direction viewpoints. All witnesses stated Bahri was crossing inside a marked crosswalk with the walk indication displayed on the pedestrian traffic control device.

Mixon was tested for alcohol and drugs following the accident. The results for both tests were negative.

A search warrant was obtained for Mixon's cell phone records. His cell phone records showed that no phone calls or text messages were made or received the day of the accident until after the accident had happened.

There was no surveillance footage of the accident.

Bahri was a student at Horizons School on Birmingham's Southside. She was one of 41 students at the school for special needs, ages 18 to 26. The school teaches independent living.

Dr. Jade Carter, executive director at Horizons, said Bahri had just finished a cooking class where she had helped to make soup. She and a group of friends were walking back to their school-owned apartment complex two blocks away.

Bahri was in her second-year at Horizons and preparing to graduate in May. A 2000 article published in Bahri's hometown in Virginia chronicled Bahri's radical brain surgery at age 3. According to that article on Fairfaxtimes.com, doctors removed the right hemisphere of Bahri's brain to treat seizures.

She suffered from a rare condition known as Rasmussen's Enchephalitis, which is a progressive neurological disorder that results in severe seizures, loss of motor skills and speech, paralysis, inflammation of the brain and mental deterioration.
