The two men accused of killing a Miamisburg woman and placing her body on train tracks are being arraigned today.

Josh Sellers, 26, and Jamie Shaffer, 21, are facing charges of aggravated murder, tampering with evidence, kidnapping and gross abuse of a corpse.

Shaffer's bond was set at $1 million during his arraignment in a Miamisburg court room Wednesday morning. Sellers will be arraigned Wednesday afternoon.

Police said they have the weapon used in the death of Lisa Spinks, a 2010 Miamisburg High School grad whose body was found on railroad tracks in Miamisburg on Sunday.

Prosecutors said they will seek the death penalty if the cases against the two men go to trial.

A search was conducted Tuesday at the homes of Sellers and Shaffer.

Knives, cell phones, weapons, clothing and an ID belonging to Spinks were some of the items police found at the homes, according to a search warrant affidavit News Center 7 obtained from Miamisburg courts.

According to the search warrant, Spinks had recently ended a relationship with Shaffer.

The affidavit stated Shaffer told police he hadn’t seen Spinks in awhile. Police then wrote that Shaffer claimed he was with her on the train trestle when he said she jumped off.

The report said he revised his story again, pointing the finger at Sellers, saying they joked about killing Spinks before Shaffer invited her and Sellers over Saturday night.

They walked down to the train tracks where Shaffer told police he saw Sellers with Latex gloves and knew they were going through with it.

Shaffer claimed Sellers hit her in the head multiple times with a rock, then dragged her body and placed her on the tracks, the report said.

Police said Spinks’ body was hit at least twice by trains overnight before a CSX train crew found her severed in two pieces.

Police said Sellers pointed the finger at Shaffer.

An autopsy performed by the Montgomery County Coroner on Tuesday said the official cause of death is multiple stab wounds.

Susan Howard, who lives down the street from Sellers, said the cold brutality of the murder is heartbreaking.

"I want justice, whichever way that comes out. We want to see justice come out," Howard said. "It's very disturbing. We're just living in a very disturbing time. There's no value to life to a lot of people."

Police are continuing their investigation, including looking at video from CSX and the preliminary autopsy results.

"We're working around the clock on this," said Capt. Ronald Hess.
