Rivara, characterized as a person of kindness and compassion, was struck by a 17-year-old female driver and tragically lost his life.

Heartbreakingly, Rivara's children, aged eleven and six, had to witness the devastating incident inside the family car.

During this challenging time, Tracey, Rivara's devastated aunt, has initiated a GoFundMe campaign to raise funds and support his wife, Angel.

As of now, over $62,000 has been collected, surpassing the initial goal of $30,000 through the generous contributions of supporters.

In a tribute to her nephew, Tracey writes: "Casey was the kindest, most amazing husband and father. Even his last act in this world was a sign of his compassion".

"The family is trying to figure out how to recover and keep going after this immense loss."

Tracey further recounts how Rivara encountered his life partner during high school at 17, emphasizing their profound connection.

Tracey said, 'they swiftly fell deeply in love and have remained inseparable companions for 23 years'.

The couple had the joy of raising two children together, named Sophia and James.

Tracey continues: "His family was Casey's world, and to remain even closer to them, he had recently started working at their children's school."

"He loved working at the school as he was able to positively impact other children."

The act of kindness displayed by Rivara was captured by 12-year-old William Wimsatt, who happened to be the child of another driver at the scene.

The child tells 3KCRA: "He got out of the car, he was shooing the ducks, everyone was clapping because he was being really nice."

"He helped them get up on the curb because the baby duckies were having trouble."

The Wimsatt family expressed their gratitude towards the father of two for his kind act, but sadly, he met a tragic fate moments later.

William Wimsatt recalls: "All I remember is the sound and then him flying across the intersection."

"His shoes and one of his socks were right in front of our car."

He then adds: "He was the only person to get out of the car and try and help them and probably the nicest person in the entire area. It's not fair."

In a compassionate gesture, the Wimsatt family has made a generous contribution of $1,000 to the GoFundMe page set up for the Rivara family.

According to a spokesperson from the Placer County Sheriff's Office, who spoke with NBC News, the driver involved in the incident has been cooperative, and it is unlikely that she will face charges in connection with the tragic death.

The police department has also released a statement: "The driver remained at the scene of the collision."

"Emergency first responders arrived to assist. However, the man died at the scene. The Major Accident Investigation Team was activated and responded to the area."

"No arrest was made, and the incident is still under investigation."

They add: "We would like to extend our condolences to all involved in this tragic event."
