Suspects arrested in murder of Raisin Township man

Two suspects were arraigned in Lenawee County Court on Monday in connection with the homicide case of Raisin Township resident Edward Allen Monday. Devon Douglas Snell, 20, was charged with open murder, while Tamera Marie Rosenburg, 40, was charged with obstruction of justice and being an accessory after the fact. Snell had been picked up on a probation violation and was in the Lenawee County Jail days before a break in the case was made. Rosenburg was brought in for questioning.

During a press conference, Lenawee County prosecuting attorney Burke Castleberry said the murder took place at 2985 Gady Rd. at Lee Villa Mobile Home Park, lot 21, either late night on November 24 or early morning on November 25. Rosenburg owned the residence, while Monday lived with her.

Preliminary autopsy results determined Monday, 50, died due to blunt force trauma to the head during a physical confrontation at the residence. Officials said few days before the homicide, electricity had been shut off to the trailer.

Rosenburg was Monday’s girlfriend, while Snell was an acquaintance of both Monday and Rosenburg. Multiple tips led officials to Monday’s body, found on December 10 approximately 10 feet off of Ranger Highway in Medina Township, 50 yards south of Packard Road.

Castleberry said during the press conference that he could not divulge any more information, including information on the murder weapon and motive, until the case becomes complete. 

“The investigation continues,” Castleberry said. “We’re looking at a lot of things.” Castleberry said he did not think drugs, robbery or domestic violence were related to the homicide.

The Lenawee County Sheriff’s Office has been investigating the disappearance of Monday since November 28, 2015. Around noon on November 25, Monday’s son received a text message from his father’s phone asking about Thanksgiving plans. Castleberry said he does not believe that Monday was alive at the time of the message, and that the text was not sent by Monday himself.

Monday’s pickup was located in Tecumseh on the corner of M-50 and Rogers Highway on December 4. The vehicle was abandoned and unlocked.

Officers used a helicopter and a tracking dog to search the area where the vehicle was found. The sheriff’s office credited the Lenawee County Prosecutor’s Office, the Raisin Township Police Department, the Michigan State Police Crime Lab, the Lenawee County Medical Examiner’s Office and the Tecumseh Police Department for helping with the investigation.

“We assisted once the vehicle was recovered at the stamping plant. Our officers were the first to respond to cover the vehicle,” Tecumseh Police Chief Troy Stern said. “We followed up the next day with the ground search and when the helicopter came in to search the area around the stamping plant.”

Anyone with further information on the case is asked to contact the sheriff’s office at 263.0524.
