Fremont police arrested the driver involved in a double fatal crash that left a mother and young boy dead.
The single vehicle crash happened on Paseo Padre Parkway Tuesday afternoon.
On Friday, police said they booked Gilbert Gil, 34, on two felony charges of vehicular manslaughter with gross negligence and one count of felony child endangerment.
Gil's wife Joie and their son Angelo died following a violent crash that tore the family's car in two.
Police said Gilbert Gil was taken into custody without incident and transported by ambulance to Santa Rita County Jail.
Police said early into the investigation, they believe the primary cause of the crash was unsafe speed for conditions. Traffic Officers have preliminary data estimating the speed to be in the range of 65 mph, which is twice the posted limit.
The family was from Milpitas on their way to a water park.
At the time of the crash, witnesses said the car, which was being driven by Gilbert Gil, was speeding down Paseo Padre Parkway between Chadbourne Drive and Dorne Place just before 1 p.m. They said the driver lost control and crashed into a tree.
Police said the child was restrained in the back seat but was ejected when the car split in half. The child was pronounced dead at the scene.
Gilbert Gil was also ejected and suffered major injuries, while his wife Joie was critically injured and had to be extricated from the car by firefighters. She died Wednesday.
Gilbert Gil's first court appearance will be next week.
