DAYTON — The Montgomery County Prosecutor’s Office is seeking the death penalty for two men charged in the slaying of a Miamisburg woman whose body was placed on a railroad track and run over by a freight train.

Joshua Sellers, 26, and Jamie Shaffer, 21, also both of Miamisburg, were indicted Oct. 5 on two counts of aggravated murder and other felonies.

On Wednesday, the grand jury added an aggravating circumstance to each aggravated murder count, making them eligible for execution.

“While asking for the death penalty is never an easy decision, in this case it is appropriate and justice demands it,” said Prosecutor Mathias H. Heck Jr.

Five people in the past five years have faced the death penalty in Montgomery County. None has been sentenced to death.

Of the 148 inmates currently on death row, six are from Montgomery County, the most recent added in 2006.

Two are from Greene County, one is from Warren and none is from Miami, according to the Ohio Department of Rehabilitation and Correction.

Heck said Sellers and Shaffer lured the victim, 20-year-old Lisa Elizabeth Spinks, to a secluded area in Miamisburg, where she was stabbed several times in the neck. The defendants then dragged her body to the railroad tracks, laid her across the tracks and covered her with brush, he said.

The defendants took Spinks’ cellular phone and disposed of it along with the knife used to kill her and the latex gloves they wore, Heck said.

Spinks’ body was found Sept. 25.

According to Miamisburg police, Shaffer told them that he, Sellers and Spinks walked from his apartment on South Second Street to a trestle where Bear Creek crosses the tracks. Shaffer, Spinks’ ex-boyfriend, told police he watched as Sellers beat Spinks with a rock.

According to the Montgomery County Coroner’s Office, Spinks died of multiple stab wounds to the neck.

Shaffer and Sellers have remained jailed on $1 million bonds since they were arrested Sept. 26.
