CHESTER, Calif. -- A teenager who was slain over the weekend while on his prom date was remembered Monday by family members as "the kind of kid that everyone loved."

Jennifer Carrigan and Steven Daniel Furtado, both 18, were found dead Sunday by Carrigan's mother at a house in Chester.

The Glenn County Sheriff's Department said Furtado had traveled from Willows, where he was a high school senior, to Chester to take Carrigan to her senior prom.

Neighbors told KCRA 3 that they were the victims of a brutal stabbing.

Family and friends said Furtado was a musician, scholar, athlete and Eagle Scout.

"He was the all-American boy -- the kind of kid that everyone loved and any dad would be proud to have," cousin Brandy McDonald said.

Furtado was set to graduate on June 6 from Willows High School.

Students mourned Carrigan at Chester High School on Monday. She was described as a musician and an aspiring anesthesiologist.

Two rural towns were reeling Monday after the discovery. Chester has a population of about 2,000, and there are about 6,000 people living in the Glenn County town of Willows.

When told of his sister's death, 20-year-old Billy Carrigan headed home from Berkeley.

Shortly before 7 p.m. Sunday, just before he reached Chester, Billy Carrigan crashed his Toyota Tacoma pickup truck into a stand of pine trees along Highway 36.

A spokeswoman at Enloe Medical Center in Chico said he was in critical condition Monday.

The Glenn County Sheriff's Department said Furtado had traveled from Willows, where he was a high school senior, to Chester to take Carrigan to her senior prom.

Officials delivered the news of Furtado's death to his family on Sunday evening as relatives were in the process of having a Mother's Day celebration at home.

Counseling was offered to students at Willows High School in the wake of Furtado's death.

Autopsies were scheduled for Tuesday at the Washoe County Medical Examiner's Office in Nevada.

Deputies arrested 18-year-old Reyes Carrillo Garcia in the deaths of the two teens, said Plumas County Sheriff's Patrol Cmdr. Gerry Hendrick. He said Garcia previously dated Carrigan.

Officials said Garcia is the only suspect in the case.

Garcia will be arraigned in court Tuesday on two counts of murder, officials said.
