SAN DIEGO – A man was arrested Thursday afternoon after his mother was found dead in the bathroom of an apartment where they live in the Barrio Logan area, authorities said.

At about 3:40 p.m., police received a call about a possible deceased woman in an apartment building in the 2800 block of Boston Avenue, San Diego police Lt. Matt Dobbs said. The caller said he had been unable to reach his mother by phone several times throughout the day, which he noted was unusual.

The man told dispatchers when he arrived at the apartment, he found his sibling brother inside and later located their mother who he believed to be deceased, Dobbs said.

A fight then ensued between the two brothers until the man who called police left the apartment.

Officers arrived and arrested the brother who was inside the apartment. He was taken to a local hospital with injuries to one of his legs sustained during the altercation with his brother. Police have identified him as a 30-year-old man, but did not publicly release his name.

The victim has been described by police as a 64-year-old woman.

Some apartments in the complex were being evacuated when police initially arrived on the scene, according to Dobbs. That was because police believed they were dealing with a barricaded subject based on available information. But the suspect was taken into custody without incident, he said.

Police have closed the 2800 block of Boston Avenue in both directions for the next few hours while the investigation is ongoing.
