The victims did not know the homeless man, reports police

In an unprovoked attack in downtown Los Angeles on Tuesday, a nine-year-old boy and a 25-year-old woman were stabbed critically by a homeless man. Police have confirmed that the victims did not know the assailant.

The suspect, a 40-year-old homeless man, entered a Target store at 7th and Figueroa streets in the FIGat7th shopping mall. He reportedly grabbed a kitchen knife from a shelf and attacked a young boy, threatening to kill him.

Los Angeles Police Department Chief Michael Moore said:

"...the suspect, without any further provocation, suddenly attacked and stabbed this young child in the back."

Witnesses immediately moved to help the child, whose mother was not present at the scene. The attacker moved down the aisle and stabbed a 25-year-old woman in the chest.

Police further said that he then moved to the front of the store and was confronted by an armed security officer who opened fire after the suspect moved towards him, still holding a knife. He was shot in the stomach and was pronounced dead at a hospital.

Police Chief Moore clarified late on Tuesday that while the young boy, identified as Brayden Medina, suffered a deep laceration to his left shoulder, he was in stable condition and was being monitored for potential neurological damage.

According to his family, the nine-year-old was undergoing physical therapy. The woman underwent surgery to treat her stab wound. At a news conference, the Los Angeles police chief said:

"The fact that you have an unprovoked attack on a child strikes all of us. This isn’t something that’s acceptable in Los Angeles and by no means is anywhere near the norm."

A third person was also injured in the sudden attack. The third victim was trampled while exiting the store and suffered minor facial bruising. The motive for the attack remains unknown.
