A 26-year-old man fatally stabbed his male lover in the back inside their Staten Island home early Friday, police sources said.

Antonio Bohanna, 35 – a transgendered man – stabbed his domestic partner, identified as Kamel Milhouse, in the torso during a dispute inside the home on Manor Road near Portage Avenue in Manor Heights around 12:40 a.m., sources said.

Emergency responders rushed Milhouse to Richmond County Medical Center where he died from his injuries about three hours later, sources said.

Police arrested Bohanna and charged him with murder in the second-degeee and criminal possession of a weapon, sources said.

It was not immediately clear what the couple was arguing over.
