On September 1, 2021, at 6:52 am, officers from the Lancaster City Bureau of Police were dispatched to 505 Pearl Street for a report of a stabbing.   The officers arrived at the scene and spoke with the victim, who was identified as 36 year-old Brandon Schweers.   Schweers told the officers that his body hurt all over and complained of difficulty breathing.  The officers observed visible injuries to Schweers' head and knee.  Schweers told the officers that Aaron Robertson was the person who did it and that Robertson had a knife and pepper spray.   Officers also learned that the victim's girlfriend heard her dogs barking and looked out to see Schweers on his back in a defensive position and "Aaron" was on top of him, near Schweer's head.  She said that Schweers was complaining that "Aaron" was killing him.    An ambulance transported Schweers to the hospital for treatment, but he was pronounced dead when he arrived at the hospital.   An autopsy will be performed to determine the cause and manner of Schweers death.

Detectives were able to identify Aaron Robertson, and he was interviewed by investigators on September 1, 2021.   During the interview, Robertson admitted to going to Schweers' home after seeing him sitting on his porch.   He stated that he and Schweers engaged in a verbal argument that lead to a physical fight.  Robertson admitted to striking Schweers several times in the area of his head.  Robertson also admitted to taking a knife and pepper spray to Schweers' house.   

The investigation into the circumstances that led to the assault, as well as the cause of Schweers' death are continuing.   Investigators processed the scene for evidence and have been interviewing witnesses.   Based on the investigation to this point, Robertson was taken into custody earlier today.   Detective Heather Halstead has charged  Aaron Blake Robertson with (1) count of Aggravated Assault (F-1) and (1) count of Simple Assault (M-2) before Magisterial District Judge Adam Witkonis.   Robertson is being held for processing and arraignment.    Robertson is 33 years old and resides in the 100 block of Pearl Street in Lancaster City.  

Persons charged with a crime are presumed innocent until proven guilty in court.
