ORANGEVALE -- "I'm just devastated, that's what I am," said Richard Duke.
A father is struggling to get back to normal after the death of his son.
"Since this happened, I can't start something and get it finished anymore," said Richard Duke.
And a daughter is fighting through the darkest time of her life.
"Losing my dad's probably been the hardest thing I've ever had to walk through," said Shauna Duke.
For three months, this family has been mourning after Jeff Duke was killed while riding his motorcycle on I-80 near Truckee.
"He was such a special man, anyone who met him seriously knew how special he was, he just lit up a room," said Shauna Duke.
The 57-year-old ran a business called "Duke's Animal Control." He frequently posted videos about his work and appeared on FOX40 as an animal expert.
But his life ended on Sept. 24 when the CHP says a group of bikers fired at Duke on the freeway, causing him to crash. He was on the way home from a motorcycle festival.
"We need closure," said Richard Duke.
His family is now desperately searching for answers.
"It's been really hard, and the holidays are coming up, and we're just seeking some resolution," said Shauna Duke.
His daughter has created a Facebook page, "Justice for Jeff Duke," in hopes it will help investigators find whoever is responsible for ending the life of a man loved by many.
"We've missed his phone calls every morning to check on us," said Richard Duke.
The CHP says no arrests have been made, and the investigation is ongoing.
