Pittsburgh police say triplets have been hurt, one critically, in an incident on the steps in their Brighton Heights home.
Yesterday around 8:15 p.m., police officers responded to the 3200 block of Richardson Avenue for a report of a 2-year-old child in respiratory failure.
Medics took the badly injured girl to Children's Hospital, where she is reported to be in very critical condition with head trauma.
The other two triplets also were treated at Children's for minor bruises and lacerations. They were evaluated overnight and released to their mother's custody, police said.
The children had been in the care of their mother's 20-year-old boyfriend while the mother, 25, went to play bingo.
Police declined to release the names of the mother and her boyfriend.
When officers arrived at the residence the boyfriend told them he had gone upstairs from the first floor when he noticed, at the top of the 14 steps, the three girls had followed.
The girls had been wearing plastic high-heeled shoes as they played on the stairs, and the boyfriend ordered them to return to the first floor.
As the children complied, they bumped into each other, causing all three fo them to fall. The most seriously injured of the three fell to the bottom, where she struck her head on the landing, police said.
Investigators were unclear on whether the girls had been at or near the top of the stairs when they fell.
No other children were present in the house at the time. No charges have been filed, pending further investigation by the police Sex Assault and Family Crisis Unit.
