LONG BEACH >> Police have identified the woman shot by officers while brandishing a replica handgun Saturday afternoon.

Adeline Arroyo, a 32-year-old Long Beach resident, was booked on suspicion of displaying a replica firearm in the presence of a police officer, police said. She remains in serious but stable condition at a hospital.

The nearly 2½-hour standoff between Arroyo and Long Beach police began at 9:50 a.m. when police received calls reporting a woman with a handgun near Third Street and Long Beach Boulevard.

Homicide detectives later determined Arroyo was holding a black, semi-automatic type Beretta replica handgun.

“Upon visual inspection, it does not fire standard firearm bullets; however, forensic testing has yet to be completed,” Marlene Arrona, a police spokeswoman said Sunday. “(The replica handgun) did not have an orange tip or any other indicators that would have alerted officers it was not capable of firing bullets.”

Officers were concerned about the heavy pedestrian traffic in the area and immediately set up a perimeter, police said.

Negotiations proved fruitless, however, and Arroyo stared into the distance.

Two mental evaluation teams were also unsuccessful in their negotiation attempts with Arroyo.

Police noticed she was holding an object in her right hand but kept it covered with clothing.

Police eventually called in the SWAT team to assist, but Arroyo began walking toward police while they waited for the backup to arrive.

She uncovered her right hand and walked toward the officers.

Police say they saw what appeared to be a black semi-automatic handgun, which she initially pointed at a postal service building and in the air.

Officers say they continued to negotiate with her at this point.

She then pointed the replica handgun in the officers’ direction and officers fired.

Witnesses told the Press-Telegram on Saturday they heard about 12 shots.

Long Beach Fire Department personnel were already at the scene and began treating Arroyo.

The Los Angeles County District Attorney’s Office is conducting an independent investigation of the shooting, according to their regulations regarding officer-involved shootings that occur in Los Angeles County that result in injury or death.
