Baby son in hospital after car crashThe baby’s parents, who were not identified, were in the hospital Monday after they lost their son, 8-year-old Michael, in a crash in northern California.
They were flown to Children’s Hospital of Philadelphia in critical condition, where the boy is being treated.
The boy’s mother, Lauren, told ABC News that she had been trying to find ways to get Michael back to his parents.
She said she and her husband had tried to get him back in the back seat of their SUV, but it wouldn’t budge.
She also said she had to use a seatbelt to get the baby to a safe spot in the SUV.
The couple was trying to convince Michael’s mother to stay with the family while they made arrangements to go to his funeral.
The accident happened near the intersection of Interstate 5 and California State Route 128, according to the California Highway Patrol.
It was not immediately clear what caused the crash.

A woman who was driving by saw the crash and called 911, authorities said.
The woman was able to get emergency help from the woman’s boyfriend, who drove her to a nearby hospital and performed CPR on Michael.
The California Highway Traffic Safety Administration did not immediately provide details on the woman or boyfriend.
The incident remains under investigation.
