A 23-year-old woman who was brutally beaten outside a Southern California nightclub was taken off life support and declared dead Tuesday afternoon, Santa Ana police said.

Kim Pham, 23, of Westminster, was found unconscious on the sidewalk after the fight, during which attackers beat and kicked her as she lay on the ground outside The Crosby Bar and Nightclub just after midnight Jan. 18, according to the Santa Ana Police Department.

She was pronounced dead about 12:36 p.m. Tuesday, police said.

Police on Monday announced the arrest of a Santa Ana woman in her 20s in connection with the attack, but were still seeking two other women and two men in the case.

Businesses surrounding The Crosby Bar and Nightclub raised a $5,000 reward in hopes of finding information that would lead to more arrests in the attack.

The fight began when the woman and her friends were involved in an argument with another group of females, police said. Two or three women reportedly hit and kicked the woman while she was on the ground, officials said.

Cellphone video was taken of the beating, which shows crowds surrounding the fight, watching as it happened. Security guards staffed by The Crosby were just far enough away from the fight to not see it until it was over, police said.

Family and friends gathered at the site to remember the woman, whom they called inspiring.

“She was just a person with a lot of energy,” said Emma Pham, an acquaintance of Kim Pham. “I was able to see how much influence she had on so many people."

"In her 23 years on this earth, she gave more love, accomplished way more than many people have in their whole lifetime," Emma's friend Alex Turkich said.

Anyone with information was asked to call 714-245-8390.
