The grandmother of Keith Ardell Benefield, the Dolan Springs teen-ager found killed on Pierce Ferry Road April 11, is asking for help in raising the reward being offered to help solve the four-month-old homicide.
Mohave Silent Witness is currently offering a $2,000 reward for information leading to the arrest and conviction of a suspect.
Audra Benefield, the victim's paternal grandmother, has collected more than 300 signatures in drafting a letter to Arizona Gov.
Jane Hull seeking additional help in investigating the murder.
She also plans to contact John Walsh of the television show "America's Most Wanted" to see if he will help.
"I feel I have to do something for Keith, to finish it," Benefield said.
"His death should be justified.
Justice should be done to what happened to Keith."
Benefield, who was in Arkansas when her grandson was killed, said that Keith had told her prior to being murdered that he had felt threatened living in the area and wanted to leave.
The Mohave County Sheriff's Office is investigating the death.
Benefield was found around 11 p.m.
lying on the ground at milepost 3 on Pierce Ferry Road, suffering from severe head injuries.
MCSO determined that the youth was not struck by a vehicle.
The injuries appeared to be from a blunt object such as a baseball bat.
No weapons were found, MCSO spokesman Steve Johnson said.
MCSO would not provide any further information on how the teenager was killed because of the ongoing investigation.
Benefield was discovered by friends about a mile and a half from where he lived with his father, Max Benefield and one of his two sisters.
When the teen-ager was found, he was treated by paramedics from Lake Mohave Ranchos Fire Department, then flown to Kingman Regional Medical Center where he was later pronounced dead, Johnson said.
Max Benefield, who works at a rock quarry in the Dolan Springs area, previously stated his son had been living with his mother in Salinas, Calif., before returning back to live with him earlier this year.
Benefield last saw his son around 7:20 p.m.
Keith would have been a 9th grader at Kingman High School South Campus this school year.
He had attended Mt.
Tipton Elementary School in Dolan Springs the previous school year.
