WHITTIER, Calif. — The family of an autistic teenager who died after being left alone on a school bus on a sweltering day is receiving $23.5 million from the bus company, the family’s attorneys said.

Pupil Transportation Cooperative is settling a wrongful-death lawsuit over the 2015, death of Hun Joon “Paul” Lee.

The bus carried Lee, 19, and two other special needs students to Sierra Vista Adult School.

Two students got off, but Lee was left inside the closed and sweltering bus for seven hours as outside temperatures neared 100 degrees, investigators said.

The lawsuit contended that the driver, Armando Ramirez, was distracted by sexually explicit text messages from a co-worker.

“Mr. Ramirez then returned the bus to the yard, oblivious to the fact that the nearly six-foot and over 300 pound young man was still aboard,” the family’s lawyers said.
