The 47-year-old man and his toddlers all survived the plunge due to a daring rescue by a San Diego cop.

Earlier that morning, the man reportedly took his 2-year-old twin daughters without permission from their mother.

He then sent texts to the mother, alluding that she may not see her daughters again.

Horrified, the mother called the police. She also informed them that her husband was suicidal and had taken their twin daughters.

Authorities traced the man's phone and followed him.

However, when the officers approached him, the father drove the vehicle off Sunset Cliffs with his daughters inside.

And when officers arrived at the scene, the vehicle was upside down, smashed and partially submerged.

Wiese was on the scene and over the cliff in minutes.

Speaking to ABC 10 News outlet, he said he thought of his family when he saw the man and the two girls.

He told the outlet:

"I could see him, and he had one of the girls in his arms. I have a 2-year-old daughter at home, so I imagined, 'What if that was my wife and kid down there?' You're not going to stand there on the cliff and watch it happen."

Using a 100-foot-long canine leash used for SWAT missions, Wiese propelled down the cliff to rescue them.

Wiese told NBC San Diego:

"He had both girls."

"[The dad] was holding them and trying to tread water, but they were all going under."

He added:

"One was awake and crying; the other one was pretty lifeless."

The officers safely rescued the father and daughters and took them to the hospital. They all survived the crash.

A friend later organized a GoFundMe for the family to help with medical expenses.

The GoFundMe said of the twins:

"They will need assistance for future unplanned doctor's visits… until they recover from the trauma as well as a team to get justice to keep their father in custody."

The father was booked into jail on suspicion of two counts of attempted murder, kidnapping, and child cruelty.

San Diego Police Chief David Nisleit praised Wiese for saving the lives of three survivors, adding:

"That's probably the most heroic thing I've seen in my 32 years."

According to Wiese:

All [he] care about is that those girls are going to live and have a second chance at life.
