Monterey Park shooting death toll rises to 11, including dance hall manager

California officials name two of those killed, while friends and colleagues say much-loved Mr Ma' was among dead

The death toll in a mass shooting at a ballroom dance studio in California has risen to 11 people, after health officials said that one of the people wounded in the shooting had died.

Authorities said the motive for what one lawmaker called the worst mass shooting in Los Angeles county history" remains unknown. The 72-year-old shooter died by suicide the morning after the attack, authorities said, after being stopped by police in a nearby town. Law enforcement officials searched his home in Hemet, and found a rifle, hundreds of rounds of ammunition, and evidence that he was manufacturing homemade gun silencers.
