Parolee Surrenders in Desert Pipe Bomb Death : Tragedy: He is accused of making device that killed Pearblossom woman and injured her son. She found it near her home while looking for recyclable items.

A parolee accused of manufacturing a bomb that killed a Pearblossom woman and seriously injured her son surrendered to authorities after his mother and girlfriend were arrested for allegedly aiding him, prosecutors said Monday.

Scott Douglas Hamby, 32--who officials said has a history of manufacturing and possessing explosive devices--faces a count of murder with the special circumstance of causing death by an explosion, which could make him eligible for the death penalty if he is convicted.

Hamby is accused of killing Lynn Standish, 33, a single mother of three, who died May 20 when she discovered a pipe bomb while hunting for recyclable goods in a desert area near her home.

Deputy Dist. Atty. John Spillane said law enforcement authorities had been actively searching for Hamby recently after receiving a tip that he was in the area. The hunt for Hamby ended without incident Sunday evening when he turned himself in to authorities at the Men’s Central Jail in Los Angeles, accompanied by his attorney, a sheriff’s spokesman said.

Authorities have said it is unclear whether Hamby intentionally left the bomb or simply discarded it along a dirt road near 106th Street, but they have said evidence discovered at the scene has linked him to the crime.

Deputy Dist. Atty. Steven D. Ogden said Hamby surrendered “only after his girlfriend and mother had been arrested for aiding a fugitive.” Authorities would not divulge how Hamby’s girlfriend and mother had aided him.

In addition to the murder count, Hamby also faces charges of possessing an explosive device and exploding a destructive device causing an injury and a death.

Wounded in the explosion was Standish’s youngest son, who suffered leg injuries but is doing “just great,” said Keith Holmes, 63, Standish’s father. Holmes said he and his wife have been caring for their daughter’s sons, ages 4, 9, and 15, since her death.

“They have been through an awful lot of trauma,” Holmes said.

Ogden said his office has not decided whether to seek the death penalty against Hamby, who is scheduled to be arraigned Dec. 16. But Holmes said he hopes Hamby is executed if he is convicted.

“An eye for an eye, a tooth for a tooth. If he actually did it then let him die too,” Holmes said. “I loved this daughter of mine, I loved her dearly.”

Hamby’s attorney, Lorn Aiken, maintained that his client is innocent of the charges.

Hamby was arrested in 1989 on criminal conspiracy charges and again in 1992 on suspicion of drug use and firearms violations and on suspicion of possessing ammunition while on parole.

After the 1992 arrest Hamby was returned to prison and was released in December of the same year, but he allegedly continued to use drugs and in August, 1993, his parole was suspended and a warrant was issued for his arrest, authorities said. An additional arrest warrant was subsequently issued in connection with the Standish killing.

In a related case, prosecutors said Hamby’s brother, Paul Hamby, was convicted in June and sentenced to two years in prison for intimidating witnesses linked to the Standish case.

In one incident, Paul Hamby intimidated a female witness when he repeatedly drove “past her house and threatened to kill her if she testified against his brother,” Deputy Dist. Atty. Ron Smalstig said. “He also drove up to her house and broke all the windows out of her car.”
