The former Schuylkill Haven man charged in Lancaster County with abuse of his mother’s corpse has been charged with murder and assault.

The Lancaster County District Attorney’s office said Monday a warrant was issued for Kevin Ahn in April on two counts of murder and two counts of assault. The charges, both in the first degree, were filed in Baltimore County, Maryland. Further information was not available.

The district attorney’s office had said additional charges are possible.

Ahn, 31, remains in Lancaster County Prison, according to prison records. He was denied bail because of the possibility of failure to appear for a court hearing, and in the interest of public safety, court records show.

In March, authorities found the body of Hyun Ahn, 61, of Owings Mills, Maryland, in her Toyota RAV4.

The woman’s death was ruled a homicide, according to the Lancaster County Coroner’s Office, which said the primary cause of death was strangulation.

The victim is the suspect’s mother and died on March 24, the coroner said.

Ahn, who was scheduled for a formal arraignment at the Lancaster County Courthouse, waived his arraignment on the misdemeanor charges of abuse of a corpse charge, court records show.

A police sergeant from the NLCRP and a detective both testified at Ahn’s hearing previously, according to the Lancaster County District Attorney’s Facebook page.

The detective said a surveillance video showed both the defendant and his mother in the vehicle about two days before she was found dead, according to the post, adding that she went inside a Lancaster County business at some point.

Prior to his arrest, Kevin Ahn’s sister told police her estranged brother was “talking in numbers ” and speaking gibberish.

She said her brother wrote a note while sitting in their mother’s Toyota RAV4, according to police.

The suspect fled the area in the RAV4 after being asked about the note. When he returned about 30 minutes later, his sister noticed what appeared to be a human leg under clothing and other items in the back seat.

“Mom is in the car. I’m sorry Please give her a funeral. My brain is fried. My mom lied, she gave me fake money from the N.A. so did my employees I lost my mind, Foregive me. Please call my sister.”

Police from Manheim and the NLCRPD found Kevin Ahn in Manheim Borough after he ran from the scene.

Police could see the victim inside the SUV, and a magisterial district judge approved a search warrant for the RAV4. The body of Hyun Ahn was found in the rear passenger side, with items piled on top of her.

Police observed hemorrhaging in her eyes and what appeared to be ligature marks on her neck, documents state.
