A 6-year-old boy walking to school was killed by a tractor-trailer at a Harlem intersection without a crossing guard.
Police say Amar Diarrassouba was hit around 8 a.m. Thursday.
"What we're saying is that she was not on post when the accident happened," Police Commissioner Ray Kelly said. "Thats all we can say at this time is that she wasn't there."
The whereabouts of the crossing guard is being investigated. According to police, she called in to say she was at her post, but was not.
The first-grader was walking with his 9-year-old brother to P.S. 155 when the accident occurred. The brother was not hurt.
The crossing guard, who has spent a decade on the job, was suspended, police said. She is not likely to face criminal charges but may face administrative charges, according to authorities.
Crossing guards are allowed short breaks but must log in the times they leave and return.
The truck driver was issued a ticket for failing to yield to a pedestrian.
