POMONA (AP) — Two women died from suspected drug overdoses at a popular weekend music festival at the Los Angeles County fairgrounds, prompting calls for an investigation and concern over the use of drugs at youth-oriented events. The women, one 18 years old and the other 19, were found unresponsive on Saturday at the HARD Summer music festival in Pomona, about 30 miles east of downtown Los Angeles. They were hospitalized but died within hours of each other, authorities said.
