Police have made a second arrest in a deadly stabbing.

Mark Ellis was taken into custody in Philadelphia Wednesday afternoon in connection with the death of 49-year-old Stephen Leibensperger.

Leibensperger was stabbed to death at a house in the 700 block of Chestnut Street in Shoemakersville, Berks County, Monday.

Police have already arrested Ellis' son, 29-year-old Michael Walker.

They said Walker became jealous when Leibensperger moved in with a man he had been romantically involved with.

Ellis is in the process of being transported back to Berks County.

Police are still looking for a third man, 21-year-old Brandon Simpkins.
