Suspects George Dac Nguyen, Jennifer Ngo and Charles Nguyen were placed into custody after a judge increased their bail to $500,000 during their court appearance in Santa Clara County Superior Court on Monday.
The three had been released after each posted $10,000 bail.
Prosecutor Charles Huang says he believe a fourth suspect, Margaret Ngo, also scheduled to appear in court Monday afternoon, will receive a similar fate. A fifth suspect, Kathy Le, awaits further prosecution.
The five relatives were charged earlier this month with felony dependent-abuse and animal neglect. They each could spend up to 18 years in prison if convicted.
