Police were dispatched for a report of a stabbing at 505 Pearl Street just before 7 a.m.
The officers arrived to find Brandon Schweers, 36, of the 500 block of Pearl Street in Lancaster, with visible injuries to his head and knee, as well as having difficulty breathing.
Prior to being taken to the hospital, Schweers told the officers that Aaron Robertson was the person who attacked with a knife and pepper spray.
During their investigation the officers spoke with the victim's girlfriend.
She heard dogs barking and looked out a window to see Schweers on his back in a defensive position and Robertson was on top of him, near Schweers' head, according to a statement released by police.
Schweers was heard saying, "Aaron is going to kill me," as the girlfriend stated to police.
Aaron Blake Robertson, 33, of the 100 block of Pearl Street in Lancaster, was later identified and tracked down by police.
Robertson admitted to coming to Schweers' home with a knife and pepper spray and attacked him once he saw him sitting on the front porch.
Schweers died of his injuries at a local hospital.
Schweers was a father to a young girl. He is survived by her, his girlfriend and his extend family and friends.
Funeral arraignments and memorial details have not been released, as an autopsy is pending to determine the cause and manner of death.
Robertson has been charged with the following:
- Aggravated Assault (F-1)
- Simple Assault (M-2)
He is being held in the Lancaster County Prison after being denied bail because of the "likelihood of upgrade to Homicide Charge," according to court documents.
His preliminary hearing has been schedule for Sept. 15 at 9 a.m.
It is unclear what prompted Robertson to go to Schweers home in the first place. In addition to both living on the same street, both men had a history of drug possession, according to court documents, but Schweers has had a clean record since 2017 and Robertson has active charges from July including drug possession, so it's unclear if drugs played a role in this incident.
An investigation is ongoing.
