Detective Mark Edward Baker - Northern York County Regional Police Department - Pennsylvania

September 17, 2025, was a tragic day for the Northern York County Regional Police Department in Pennsylvania.  

On this date, Detective Mark Baker, Detective Isaiah Emenheiser, and Detective Sergeant Cody Becker were shot and killed.  Another detective from the Northern York County Regional Police Department and a deputy sheriff from the York County Sheriff's Office were wounded.  This had occurred while they were attempting to serve an arrest warrant in the 1800 block of Haar Road in North Codorus Township.

A man had been wanted for stalking a female and was hiding in the field near her house.  The mane was wearing camouflage, carrying an AR-15, and was using binoculars to watch her inside her home.  When detectives were unable to serve the warrant at the suspect's home, they went back to the victim female's houses.  

At approximately 2:08 p.m., the detectives approached the house and realized that the front door was unlocked.  When they entered the home, they were met with gunfire.  Detective Sergeant Becker and Detective Emenheiser were ambushed.  When Detective Baker and another detective tried to find cover, they were fire upon multiple times.  

The shooter then walked out of the house to fire at another detective and a York County Sheriff's Office deputy.  The detective and the deputy's vehicle were struck.  Both the detective and deputy returned fire, but the suspect continued to advance to the roadway until he was shot and killed.  

Unfortunately Detective Sergeant Becker, Detective Baker, and Detective Emenheiser died on scene. Another detective and the deputy were critically wounded.

Detective Mark Baker was a United States Army veteran and had served with the Norther York County Regional Police Department for over 21 years.  He had previously served with the Philadelphia Police Department.  Detective Baker was 53-years-old and is survived by his wife, four children, his mother, and two grandchildren.  

Our prayers and condolences to Detective Mark Baker's family and the Northern York County Regional Police Department.
