No easy answers to what motivated co-pilot in doomed flight

The plane was smashed to pieces on the rocky slopes of the French Alps.
Sunday Journal: More questions from Germanwings crash 02:41

LONDON - A disgruntled worker shoots up a workplace. A student opens fire at a high school. A pilot crashes a planeload of people into a mountainside.

There may never be a convincing explanation for such devastating acts of violence, but experts say certain personality disorders such as extreme narcissism can help push people who want to take their own lives to take those of others at the same time.

But as German prosecutors search for what might have motivated co-pilot Andreas Lubitz to deliberately smash the Germanwings plane carrying 149 other people into the French Alps, many experts caution against speculating on a diagnosis.

"We don't have a clue what was going through his mind," said Dr. Simon Wessely, of the Institute of Psychiatry at King's College London. "Even if we had all of his medical records and had conducted interviews with him, it would probably still be impossible to explain such an inexplicable act."

Ripped-up sick notes from a doctor found at Lubitz's home by German prosecutors suggest the 27-year-old had an illness he hid from his employers at Germanwings. Medical documents showed he had an existing illness - which wasn't specified - but no suicide note was found. A Dusseldorf hospital confirmed Friday that Lubitz had been treated recently, but didn't say for what.

Neighbors of Lubitz were shocked at allegations he could have deliberately smashed the plane and said he had seemed thrilled with his job at Germanwings. They described a man whose physical health was excellent and records show Lubitz took part in several long-distance runs. Germanwings said he had passed all required medical check-ups.

Some experts said it was possible that people who commit such horrific acts of violence might be suffering from mental illnesses like narcissism or psychosis.

Dr. Raj Persaud, a fellow of Britain's Royal College of Psychiatrists, says that in cases of mass murder, people sometimes suffer from personality disorders that make them extremely self-centered. He and others were speaking generally and had no personal knowledge of the Lubitz case.

"People feel that something so terrible has been done to them that this catastrophic act is warranted in exchange," he said. "To them, it feels like the correct balance to equal what they suffered."

Others said that preventing such chilling acts of violence may be nearly impossible if there aren't any obvious warning signs or if the person is able to hide their symptoms.

"People can become quite skilled at masking their problems because it's socially undesirable," said Dr. Paul Keedwell, a psychiatrist who specializes in mood disorders at Cardiff University.

Keedwell said it would be unwise to assume Lubitz's deliberate plane crash was an aggressive act.

"It's difficult to understand, but what if he was just so wholly preoccupied with ending his own life he didn't have any regard for the other people on the airplane?" he said.

He likened it to people who throw themselves in front of trains without considering the trauma that might inflict on the driver and other passengers.

Some experts said mass murders are intended by the killer to do maximum damage, to draw attention to themselves.

"The subject wins fame by doing something the world will remember, even if it's as a negative hero," said Dr. Roland Coutanceau, president of the French League for Mental Health.

He said such acts are sometimes committed by paranoid people angry with their employer or with society at large.

"This is a destructive act that (gives) him some kind of immortality," Coutanceau said. "Death is therefore part of his script."

Meanwhile, the pastor of the Lutheran church in Lubitz's hometown said Sunday that the community stands by him and his family.

The town of Montabaur has been rattled by the revelation that Lubitz, who first learned to fly at a nearby glider club, may have intentionally caused Tuesday's crash of Germanwings Flight 9525.

"For us, it makes it particularly difficult that the only victim from Montabaur is suspected to have caused this tragedy, this crash - although this has not been finally confirmed, but a lot is indicating that - and we have to face this," pastor Michael Dietrich said.

He spoke to The Associated Press after holding a church service Sunday to commemorate the crash victims and support their families.

"The co-pilot, the family belong to our community, and we stand by this, and we embrace them and will not hide this, and want to support the family in particular," Dietrich said.

He added that there is no direct contact with the family at the moment, but that he believes they are receiving good assistance.

French prosecutors haven't questioned the family yet "out of decency and respect for their pain," Marseille prosecutor Brice Robin said.

Brice said that none of the bodies recovered so far have been identified, denying German media reports that Lubitz's body had been found.

Dietrich, the pastor, said he knew Lubitz as a teenager, when he attended religious education 13 years ago, and his mother, who worked as a part-time organist in the community.

"When I worked with her or talked to her, it was very good and very harmonious. We had good conversations," Dietrich said. "I know her and her family. This does not make sense. It is incomprehensible for me, for us, for everyone who knew her and the family."

"From what I've heard, there were no obvious signs that there is anything in the background that could lead to this," he added.

In Rome, Pope Francis on Sunday prayed for the victims of the plane crash, citing in particular the 16 German students returning from an exchange trip to Spain.

Francis offered the prayer after Palm Sunday Mass in St. Peter's Square at the start of Holy Week.
