One of the victims, a seven-month pregnant woman, lost her baby because of her injuries, the newspaper La Vanguardia reported, citing the police.
Another victim was critically injured by four bullets. His girlfriend told the police that she suspected the perpetrator to be her ex-boyfriend, who had recently been released from prison.
