As authorities on Tuesday charged a man with stabbing to death his father over the weekend in the Angeles National Forest, the victim’s friends identified him as a longtime photojournalist and educator.

“It is with deep sorrow that we share the news of the passing of our dear friend and colleague Paul Lowe, whose brilliant life was cut short in Los Angeles, California on Saturday,” V11 Photo posted on Instagram and Facebook. “Paul was a courageous and beloved comrade, and a deeply devoted father and husband. The loss is shocking and overwhelming, and our hearts go out to his wife and family.”

The Los Angeles County District Attorney’s Office filed one count of murder against Lowe’s son, 19-year-old Emir Abadzic Lowe, with the special allegation that he used a deadly weapon to commit the crime, according to court records and investigators.

The 60-year-old Paul Lowe, whom the medical examiner’s office and detectives identified as Christian Paul Lowe, died of a stab wound to the neck on Oct. 12.

Deputies checking an assault call found him lying on Mt. Baldy Road, near Stoddard Canyon Falls, that afternoon, a sheriff’s department statement said. He died at the scene.

Lowe’s son was seen driving away and crashed. Deputies arrested him based on evidence at the scene and from statements he made, according to the statement.

Investigators have not revealed a motive behind the stabbing.

Paul Lowe’s biography in the London College of Communications, University of the Arts where he worked described him as an award-winning photojournalist, author, critic and educator who has covered the fall of the Berlin Wall, Nelson Mandela’s release, famine in Africa, the conflict in the former Yugoslavia and the destruction of Grozny.

The Embassy of Bosnia and Herzegovina in the United Kingdom posted on its Facebook account about they were deeply saddened to hear the news of the sudden death of Lowe.

“Paul was a true friend of Bosnia and Herzegovina, a wonderful human being, a great artist and professional, loved and respected by all who knew him,” the embassy said. “Our deepest condolences to Paul’s wife Amra Abadzic Lowe, their family and many friends. The Memory and the important work and legacy of Paul Lowe will continue for future generations. May he rest in peace.”

Paul Lowe was a contributing photographer to The VII Foundation, a nonprofit which “trains and equips emerging visual journalists from communities underrepresented in the media,” according to its website. VII Photo is part of the foundation.

“Paul was always trying to do good in the world,” said Ron Haviv, director and co-founder of the foundation. He has known Lowe for more than 30 years.

Lowe was involved with the foundation since its inception, he said.

Lowe’s home was in Sarajevo and he worked in London, Haviv said, adding Lowe has taught hundreds of students, several of whom have won Pulitzers.

“Paul led multiple lives as a working photographer and academic,” Haviv said.

Even if Lowe’s life was cut short, the impact of Lowe’s life and work should be remembered, he said.

Other friends, students and colleagues of Lowe posted on social media about how his death was devastating to them and how they would miss him. One described him as a great man while another called him a gentleman.
