A family is grieving the loss of three brothers killed in a head-on DUI crash.

The crash happened about 3:45 p.m. Saturday on State Road 113 near Schlagle Road.

"They're no longer going to be able to watch their kids grow," Alexis Flores, the victims' sister-in-law, said.

Flores said 21-year-old Carlos Blanco, 19-year-old Antonio Blanco, and 15-year-old Lucas Blanco were riding in their 1991 Honda Accord on State Road 113, when Michael Allan Jones slammed his 2007 Ford F-250 into them.

Neighbor Jon Christy ran out of his house to see the mangled mess.

"I heard a loud boom, and my dad called 911, the car was smoking, and within a minute, maybe, it burst into flames," Christy said.

Passers-by like George Smith immediately jumped out of their cars to help.

"One of the gentlemen was a volunteer fireman, and he actually started watering down the car, and I was on the other side trying to use a fire extinguisher, but it just didn't work," Smith said.

Smith said a woman threw him a fire extinguisher to battle the flames, but it was too small, and too late.

"I wish I could have helped, but the heat was just too hot. I can feel my facial hair… it was about to melt," Smith said.

California Highway Patrol said Jones, 38, of Oroville, lost control of his truck, veered onto the wrong side of the road, and struck the Blancos' car, flipping it. The brothers were pinned underneath the burning car. The three were declared dead at the scene.

After crews battled the fire, Jones was arrested on suspicion of felony DUI and manslaughter.

"The mother and grandmother showed up, and as soon as the mother found out, she just straight up passed out right there," Smith said. "She just couldn't believe that her three boys were killed."

Lucas is a high school student.

Carlos leaves behind a baby daughter.

Antonio leaves behind a son and a pregnant wife, due any day.

"Today was supposed to be my sister's baby shower. That's obviously not going to happen anymore," Flores said.

The family is now forced to plan three funerals. They are still wondering how they will ever tell their young ones how their fathers left the earth.

"They're still so young, they don't know what is even going to happen, what has happened," Flores said. "Just know that they were great parents, they were great people and that they were loved very, very much."
