Paul Lowe, an award-winning British photojournalist who captured the horror of war during the fall of the former Yugoslavia in a career that spanned decades and continents, was killed in a stabbing near Los Angeles on Saturday. He was 60.

The Los Angeles County District Attorney’s Office filed one count of murder against Mr. Lowe’s son, Emir Abadzic Lowe, 19, for the death, in the San Gabriel Mountains, the county’s Sheriff’s Department said in a statement on Tuesday. The county’s medical examiner said Mr. Lowe had died from a stab wound in the neck.

Mr. Lowe’s work as a photojournalist encompassed several conflicts and major historical events, including the fall of the Berlin Wall and the Russian invasion of Grozny in Chechnya. His best-known photographs emerged out of the siege of Sarajevo, in Bosnia and Herzegovina, one of the longest sieges of a capital city in modern history.

His son had long struggled with his mental health and was hospitalized on multiple occasions for psychosis over the past year, said Amra Abadzic Lowe, Mr. Lowe’s wife of almost 30 years.

Their son took a trip to the United States that was supposed to last days, but he had not returned after more than two months. Mr. Lowe traveled to California to try to persuade him to come home with him.
