PARIS (AP) -- French officials were conducting an autopsy Sunday to determine whether a suspected Islamic extremist was drunk or high on drugs when he took a soldier hostage at Paris' Orly Airport and was shot dead by her fellow patrolmen.
The suspect, Ziyed Ben Belgacem, stopped at a bar in the wee hours Saturday morning, around four hours before he first fired bird shot at traffic police. Then, 90 minutes later, he attacked the military patrol at Orly, causing panic and the shutdown of the French capital's second-biggest airport.
A subsequent police search of his flat found cocaine, Paris prosecutor Francois Molins said.
In an interview Sunday with French radio Europe 1, a man identified as the suspect's father said Belgacem wasn't a practicing Muslim and drank alcohol.
"My son was never a terrorist. He never attended prayer. He drank. But under the effects of alcohol and cannabis, this is where one ends up," said the father. Europe 1 did not give his name.
The Paris prosecutor's office, which is in charge of the probe, said Sunday that Belgacem's father was released from police custody overnight. His brother and a cousin were still being questioned.
In a news conference late Saturday, Molins said Belgacem called his father and brother early that morning, minutes after he fired bird shot at a police traffic patrol, injuring an officer in the face, to say that he'd made a stupid mistake.
"He called me at seven, eight in the morning and said, `there you go, Papa.' He was extremely angry, even his mother couldn't understand him," the man identified as the father said on Europe 1. "He told me, `I ask for your forgiveness. I've screwed up with a gendarme."'
Blood samples taken during Sunday's autopsy were to be screened for drugs and alcohol, the prosecutors' office said.
The 39-year-old Frenchman had a long criminal record, with multiple jail terms for drugs and robbery offences.
Molins said Belgacem was out on bail, banned from leaving France and obliged to report regularly to police, having been handed preliminary charges for robberies in 2016. He was also flagged as having been radicalized during a spell in detention from 2011-2012, Molins said. His house was among scores searched in November 2015 in the immediate aftermath of suicide bomb-and-gun attacks that killed 130 people in Paris.
Yelling that he wanted to kill and die for Allah, Belgacem wrested away the soldier's assault rifle during the Saturday morning airport attack but was shot and killed by her two colleagues before he could fire the military-grade weapon in Orly's busy South Terminal.
"With a pistol in his right hand and a bag over his shoulder, he grabbed (the soldier) with his left arm, made her move backward by three to four meters (yards), positioning her as a shield, and pointed his revolver at her forehead," Molins said.
According to soldiers, the attacker yelled: "Put down your weapons! Put your hands on your head! I am here to die for Allah. Whatever happens, there will be deaths," Molins added.
The attack forced both of the airport's terminals to shut down and evacuate, sent passengers and workers fleeing in panic and trapped hundreds of others aboard flights that had just landed. It was the violent climax of what authorities described as a 90-minute spree of destructive criminality across Paris by the suspect.
The fearsome drama -- which caused no injuries aside to the lightly-wounded traffic police officer -- further rattled France, which remains under a state of emergency after attacks in the past two years that have killed 235 people.
