Two men were killed and several people including an infant were injured in two separate Huntington Beach car crashes that happened within 24 hours of each other.

Abraham Perez, 30, was pronounced dead at the scene about 7:30 a.m. Wednesday after a collision at Bolsa Chica Street and Tasman Drive, Lt. Mitch O'Brien said. The driver of an orange 1973 Ford Bronco lost control, crossed over the center divider and hit Perez's silver 2000 Honda Civic.

The 20-year-old Bronco driver, whose name has not been released, was in the car with her 7-month-old daughter. The woman was treated for minor injures, but the baby sustained severe injuries and remains in critical condition, according to police.

Several other people were treated for minor injuries at the scene.

Then, about 1:55 a.m. Thursday, a 2011 Dodge Ram tow truck crashed into the rear end of a 2001 Chevrolet Impala parked along the west curb of Springdale Street with a 77-year-old Huntington Beach man and his 13-year-old grandson sitting inside, O'Brien said.

It was unclear why the man and his grandson were sitting in the parked car at that hour.

The man and the boy were treated at the scene then transported to a local hospital, where the man was pronounced dead. His name has not been released pending notification of next of kin, O'Brien said.

The boy was treated for minor injuries.

The 38-year-old tow truck driver was not injured.

No citations or arrests were issued for either incident, but the investigations for both are ongoing, O'Brien said.

Anyone with information is encouraged to contact Officer Bob Barr at (714) 536-5666 or Officer Dennis Fulton at (714) 536-5670, respectively.
