HAMILTON, Ohio (Scripps News Cincinnati) — An arraignment is scheduled Monday for what was one of the biggest cold cases in the Tri-State.

John Carter is expected to be in court at 10:30 a.m. after being charged with murder in connection to the 2011 death of his fiancé, Katelyn Marhkam.

Newly released police body cam footage from the Forest Park Police Department shows the moment Carter was arrested last week.


John Carter was taken into custody Wednesday by the Forest Park Police Department for the murder of Katelyn Markham.

The body cam video shows Carter in handcuffs being patted down by officers before he’s put in the back of a police cruiser. A camera inside the police cruiser shows Carter sitting in the back of a cruiser. There is no audio on the video so it is unclear if Carter was saying anything. Carter is then taken out of the cruiser by police.

Carter’s indictment was unsealed Thursday morning, revealing the first official court documents that tie Carter to Markham’s death. Documents show Carter has been charged with two counts of felony murder. Butler County Prosecutor Michael Gmoser said he is being held at the Butler County Jail.

According to the Butler County Clerk of Courts, Carter is set to be arraigned at 10:30 a.m. on Monday, March 27 by Judge Daniel E. Haughey.

This massive break in Markham’s case more than a decade after her disappearance brings her family one step closer to the truth.

Markham was a 22-year-old art student residing in Fairfield when she vanished in August 2011. She did not show up for work at David’s Bridal near Tri-County Mall and Carter later called 911 to report her missing.

In the call, Carter said, “I know you’re not supposed to report a missing person before 24 hours, but my fiancée is missing, and I can’t find her anywhere.”

Markham left her car, keys, dog and all personal belongings with the exception of her cell phone at her townhouse. Her cell phone was turned off at about 12:45 a.m. on Aug. 14, 2011. The GPS device on her phone also was turned off.

Markham’s skeletal remains were found in August 2013, in a remote wooded area in Indiana about 30 miles from her home. Her death was ruled a homicide, but the cause of death has never been determined.

According to court documents, Carter allegedly killed her between August 13 and August 14, 2011.
