Klein was a drug and alcohol counselor. On Friday night, he was helping people in a DUI program. Less than two hours later, police say an intoxicated driver killed him.
Klein was never happier than he was when he was on his Harley with his girlfriend. That's where he was Friday night when police say a driver going 100 miles per hour on Fresno streets slammed into his motorcycle and killed him. His Harley laid in pieces on McKinley.
"He went with the person that he loved, doing the thing that he loved the most," said his friend Len Girardeau.
The car got smashed right down the middle, but police say the driver kept going until it broke down. They caught him a few blocks away.
Jose Calderon now faces manslaughter charges as well as DUI and hit and run. He bailed out of jail after just a few hours, but Klein's family isn't angry. They say, at one time, the intoxicated driver could've been Klein himself.
"That man, whoever he is and wherever he is, is in the same place that my brother once was and god willing, that didn't happen to my brother, but it might have," said his sister, Rocki Ramsey.
Klein overcame addictions to become a drug and alcohol counselor at Madera County Behavioral Health Services, and in Fresno.
His death leaves about 50 drug addicts and alcoholics without their counselor. But fellow counselors say they're already seeing an impact when they talk about how their friend died.
"I'm hoping that in some way, my friend's death will have a positive impact some way on someone who will say, 'I'm not going to be the one to do that to someone else,'" said Girardeau. "I mean, that's all we can hope for."
Jeri Perry is in critical condition at Community Regional Medical Center, although friends say she's getting a little better.
Her 17-year-old son is in town now. He's due to graduate from high school in two months and hoping his mom can be there for the ceremony.
