Eleven-year-old Natalie Tezsla was released Wednesday afternoon. But her sister, Sophie, and another student, 11-year-old Jonathan Zdybel, remained hospitalized in critical condition.
The school bus and a dump truck collided Feb. 16 in Chesterfield, killing Isabelle Tezsla. Authorities said 17 of the 25 elementary school students on the bus were injured.
The triplets' father, Anthony Tezsla, is a state police sergeant.
The crash is under investigation by local authorities and the National Transportation Safety Board; no charges have been filed.
