Police believe the stabbing spree began with an attack on the day care worker. The father intervened in the conflict and was stabbed as well. Afterward the attack on the children started, while another unidentified person called 911. It was unclear if one of the children that was stabbed belonged to the father.

Officials report that the location reportedly had paperwork indicating that it was a day care facility but they are unclear why so many newborns were there at the time. Nine babies — five girls, four boys were at the day care. Other parents were reported to be present at the time as well.
