Authorities have arrested a man suspected of shooting and killing a woman Monday in Pasadena following a standoff in an apartment that dragged on for hours.

Around 10 a.m., Pasadena police responded to the 200 block of South Raymond Avenue on reports of several shots fired. Upon arrival, they found Jamila Elysse Moss, 34, of Pasadena, “unresponsive with fatal injuries,” a news release from the Pasadena Police Department stated.

The suspected gunman, identified as Guary Lonnie Shuford III, 32, of Los Angeles, was eventually tracked down to an apartment complex near the intersection of Del Mar Boulevard and Raymond Avenue.

Authorities were unable to contact the suspect at first, which led to a sweep of the building. They eventually located the apartment where Shuford was believed to be located and began negotiating his surrender.

Pasadena police were assisted by the Glendale Police Department and a SWAT Team.

Video from the scene showed at least two armored vehicles and several heavily armed law enforcement officers surrounding the apartment building, which was located near a Metro station.

A black Toyota RAV4 could also be seen near the scene, surrounded by police vehicles and crime scene tape, although its connection to the crime was unclear.

The video also appeared to show one person handcuffed and speaking to officers, but police have not said if the person seen was involved or if that person was ultimately arrested.

The public was asked to avoid the area, and Metro A Line rail service was interrupted between the Fillmore and Memorial Park stations during the barricade situation.

Shuford eventually surrendered himself to police and was taken into custody without incident, authorities said, adding that homicide investigators have taken over the case.

The relationship between Shuford and Moss is unclear at this time, but investigators say domestic violence is suspected.

Shuford was booked into jail to await charges for murder. He’s currently being held without bail and was expected to appear in court on Tuesday. He has a previous conviction for robbery and was on parole at the time of the deadly shooting, police said.

A GoFundMe campaign was created to help Moss’ family, with a portion of the proceeds to be donated to an organization for domestic violence victims.
