Two of Oklahoma City police officer Chad Peery's children remain hospitalized Tuesday, a hospital spokeswoman said.
McKinsey Peery, 13, is reported to be in good condition and Mason Peery, 11, in fair condition at OU Medical Center.
McKade Peery, 7, and Morgan Peery, 5, have been discharged, the hospital spokeswoman said.
The children were riding a van Sunday on Interstate 40 when a tire blew out and the van crashed. Their father, who also was in the van, died Monday as a result of the rollover crash. The van's driver, Shelby Palmer, 19, was released from the hospital Monday.
