The Alameda County Sheriff's Office Coroner's Bureau has released the names of two women who died from injuries sustained in Fremont early Sunday when they fell from a balcony during an apartment complex fire.

"It's unclear if the two people attempting to escape the intense fire conditions fell from the fourth-floor balcony or were attempting to leap (or escape) to the balcony area below the fire unit," spokeswoman Aisha Knowles said in an email Sunday afternoon.

One person died and three were injured in an early morning apartment building fire in Fremont Sunday, fire officials said.
