A man has been charged with the fatal stabbing Saturday of his father in Jefferson Hills.

Allegheny County Police charged Kabir Buhari, 42, of Jefferson Hills with criminal homicide in the death of Alhaji Buhari.

The U.S. Marshal’s Fugitive Task Force and Maryland’s Montgomery County Police Department arrested Buhari on Monday at a hotel in Bethesda, Maryland.

Witness interviews and unspecified “additional evidence collected at the scene” led detectives to determine Buhari was responsible for killing his father, county police said in a post on social media.

A criminal complaint outlining the evidence against Buhari was not available Monday evening because it is under seal, according to Jim Madalinsky, a county police spokesman.

Police said 911 was notified just after 4 p.m. Saturday about an unresponsive male in the 100 block of Arnoni Drive.

First responders found Alhaji Buhari with multiple stab wounds. The 69-year-old man was pronounced dead at the scene.

His son fled, police said.

Detectives learned Kabir Buhari might be at a Bethesda hotel and picked him up Monday morning.

Buhari is being held in Montgomery County pending extradition to Allegheny County.

He was charged in April by Bethel Park police with unsworn falsification to authorities and the illegal sale or transfer of firearms.

According to the criminal complaint in that case, Buhari went to Allegheny Arms to buy a Smith and Wesson handgun on Jan. 3.

However, when a store employee ran him through a state background check, Buhari was denied because he had a previous involuntary commitment to Jefferson Hospital for psychiatric care on Aug. 18.

He was committed against three days after he tried to buy the gun.

Under Pennsylvania law, a mental health commitment prohibits a person from purchasing a firearm.

On the federal forms Buhari filled out to buy the gun, the criminal complaint said, he denied ever having been committed to a mental hospital.
