MONTEREY PARK, Calif. (AP) – The search for the motive behind the shooting massacre at a Los Angeles-area ballroom dance hall led police to a mobile home community. Authorities say Huu Can Tran killed 11 people at a Monterey Park dance hall and attempted a shooting later at another club before taking his own life. Police in his town of Hemet say he alleged earlier this month that he was the victim of fraud, theft and poisoning by relatives a decade or two ago, but didn’t provide supporting documents he promised. The death toll rose to 11 after health officials announced that one of the 10 people wounded had died.
