'Everybody would have died' -Hero disarms California shooter

STORY: Police identified 72-year-old Huu Can Tran as the suspect in Saturday night's massacre, which took place over the Lunar New Year, one of the most festive holidays in Asian cultures.

Officials worked into Monday trying to identify the 10 people Tran allegedly killed at the Star Ballroom Dance Studio in Monterey Park, about 7 miles (11 km) east of downtown Los Angeles. Ten people were wounded in the attack, and seven of them were still hospitalized late Sunday.

Tran's rampage could have been worse. About 20 minutes after the shooting in Monterey Park, he entered the Lai Lai Ballroom & Studio dance club in the neighboring city of Alhambra. There, Brandon Tsay, who operates the family-run dance hall, wrestled a weapon away from the shooter before he could get a shot off.

"We struggled into the lobby trying to get this gun away from each other. He was hitting me across the face, bashing the back of my head. I was trying to use my elbows to separate the gun away from him, create some distance. Finally, at one point, I was able to pull the gun away from him, shove him aside, create some distance, point the gun at him, intimidate him. I shout at him and say, 'Get the hell out of here! I'll shoot! Get away! Go!'" Tsay told ABC's Good Morning America.

About 12 hours later, police officers in Torrance, 20 miles southwest of Monterey Park, approached a white cargo van that Tran was driving. As officers neared the van, they heard a single gun shot from inside as Tran killed himself.
