Four children are safe and their father is in custody following a dramatic standoff today on a freeway ramp in San Diego.

According to the Montebello Police Department, police responded to a locator device in a vehicle belonging to Daniel Diego Perez, who was considered a person of interest after he, his wife and his four children were reported missing on December 9.

An unidentified woman was found deceased in the trunk of the family's vehicle on Wednesday.

Video shows Perez parking a second vehicle on the transition ramp on Route 52 in San Diego. Shortly after, two children are able to escape from the car.

Perez then exited with the other two children and moved toward the edge of the ramp. When he lifted a leg over the edge of the ramp, officers quickly rushed him and successfully detained him.

Captain Luis Lopez, of the Montebello Police Department, said while the investigation is ongoing, there is a history of domestic violence in the family. He says extended family were in touch with the department and voiced concern over the safety of the children.

"Now that the children are out of harm's way, I'm sure they're going to very excited." he said.

Lopez said officers will now try to identify the body found in the other vehicle. He said as of right now, Perez is not considered a suspect in that homicide.
