A child died Sunday after a hit-and-run car crash in North Hills sent one vehicle careening onto a sidewalk and into his stroller, police said.

The crash occurred in the 15500 block of West Nordhoff Street near Langdon Avenue, where Officer Cervantes of the LAPD said two vehicles, a Honda HR-V and a gray Toyota Camry, collided at about 7:35 a.m.

The force of the wreck sent the Honda over a curb, where it hit an adult woman and a 1-and-a-half-year-old boy who were walking on the sidewalk, Cervantes said.

The family of the slain child identified him as Sebastian Chavez and said the woman is his grandmother.

Chavez was transported to a local hospital in critical condition, and he later succumbed to his injuries. The woman was transported in serious condition, according to the Los Angeles Fire Department, but she returned home later on Sunday, according to her family.

Chavez’s grandfather, Alfredo Morales, said he heard “the impact of the cars” and turned to see the vehicle pinning the child’s stroller against a brick wall.

“As soon as I hear that, the car went to my grandson,” Morales said.

Ana Morales, Chavez’s mother, called the experience “so painful, it’s something I would never wish on anyone.”

Ana Morales added that Chavez was born prematurely and spent more than two months in the newborn intensive care unit.

“I watched him fight for his life when he was just born, and it’s crazy that an accident like this has taken him from me,” Morales said.

Chavez’s neighbors said they’re heartbroken for the family.

“It’s so, so, extremely so sad,” neighbor Juan Hurtado said.

A GoFundMe page has been organized on behalf of the family.

The LAPD is investigating and has not yet determined if alcohol, drugs or speed were a factor in the crash, Cervantes said, though the investigation is treating the case as a hit-and-run.

The driver of the Honda remained on scene after the wreck, but the Toyota left the scene, Cervantes said.

The driver of the Toyota met with officers at the LAPD Valley Traffic Station between 4 and 4:30 p.m. Sunday and provided their information and a statement, according to Officer Fatool.

As of Sunday evening, they are cooperating with investigators and are not under arrest, Fatool added.
