Killer of teens in 1978 given 2 life sentences

Los Angeles Daily News

June 2, 2004

SAN BERNARDINO - The one memory that has played itself over and over again in Caroline Zeoli's mind is how her children were killed in cold blood by a man named William Floyd Zamastil.

Zamastil, 52, was sentenced Tuesday to two terms of 25 years to life for the bludgeoning deaths of Jacqueline Bradshaw, 18, and her 17-year-old brother, Malcolm. The Canoga Park siblings were hitchhiking home from Las Vegas when Zamastil picked them up at a Barstow gas station on Feb. 27, 1978, the last time they were ever seen alive.


Convicted killer pleads guilty to murdering 2 Valley teens

SAN BERNARDINO - Convicted killer William Floyd Zamastil pleaded guilty on Friday to the February 1978 bludgeoning murders of a Canoga Park brother and sister near Barstow.

Zamastil, 52, will avoid the death penalty and serve 25 years to life in prison for the beating deaths of Jacqueline Bradshaw, 18, and her brother Malcolm, 17. The murder sentence will run concurrently with a 25 years to life sentence Zamastil is serving in Wisconsin for rape and murder in that state.

The plea bargain struck with county prosecutors closes the 26- year-old murder case 13 months after it was reopened by the Sheriff's Department. Zamastil likely will never see the inside of a California prison.


Wisconsin killer extradited to California

Saturday, September 20, 2003 -

SAN BERNARDINO, California (AP) -- A man accused of clubbing to death a brother and sister 25 years ago in the Mojave Desert was extradited Thursday from Wisconsin to face capital murder charges.

William F. Zamastil, 51, is charged with the 1978 robbery and murders of Malcolm Bradshaw, 17, and his sister Jacqueline, 18, of Los Angeles.

Sheriff's deputies escorted Zamastil from a Wisconsin prison where he was serving time for murder.

"We're happy to have him back here," prosecutor Dave Whitney said. "He would have been eligible for parole next year."

When Zamastil was charged in June, Whitney would not say why the case was revived after so many years.

In 1982, Zamastil admitted the slayings in a telephone interview with a San Bernardino County detective, officials said. He was charged with the murder of Jacqueline Bradshaw two years later, but for undisclosed reasons the case was not prosecuted.

The Bradshaws were killed while hitchhiking home from Las Vegas to Los Angeles after helping a friend move. Autopsies showed they died of blunt-force injuries to the head.

Whitney said authorities were trying to determine if Zamastil might be connected to as many as five other killings in California and Arizona.
