EAST FALLS -- A 7-week-old girl injured in a crash in the East Falls section of Philadelphia last week has died of her injuries.
Action News is told Zyana Wilson-Perez was pronounced dead at 7:15 p.m. Thursday at St. Christopher's Hospital for Children.
At the time of the crash, Philadelphia police said she was in a child safety seat, but were not sure if it was properly installed.
Three adults and three other children in the car were not wearing seat belts.
Twenty-year-old Zaire Ross-Wilson and 6-year-old Eric Barksdale-Perez were killed in the crash.
Ross-Wilson was the father of Zyana.
The crash happened shortly before 4 p.m. May 1 in the 5400 block of Henry Avenue, near School House Lane.
Investigators say the rainy weather was a major factor.
Police say a gray Mazda 6 was travelling northbound with two women in the front seats. The 20-year-old man, 6-year-old boy, the baby girl and two other boys were in the back seat.
Witnesses tell police the Mazda 6 was spinning in the northbound lanes, crossed into the southbound lane and went into the path of a blue Mazda 3 with a man and woman in the front seats.
The driver of the Mazda 3 had no time to swerve, witnesses tell police, and it hit the Mazda 6 in a 'T-bone' style crash.
After the wreck, police say an off-duty officer arrived on the scene and started CPR on the 6-year-old boy, who was partially ejected from the Mazda 6. He did not survive.
Meanwhile, another off-duty officer arrived and assisted with CPR, which was also performed on the infant.
Zyana Wilson-Perez suffered a severe brain injury and a severe abdominal injury.
Both adults riding in the front of the Mazda 6 were ejected, police say.
Those front seat passengers, a 25-year-old woman and a 23-year-old woman, were critically injured.
The other two children in the car, a 4-year-old boy and a 5-year-old boy, were treated for internal injuries.
Meanwhile, the driver of the Mazda 3, a 29-year-old man, suffered a laceration to a leg, while his 28-year-old female passenger suffered severe injuries to both legs.
