The suspects, ranging in age from 18 to 22, are all residents of La Puente. Deputies said they recovered at least $12,000 worth of allegedly stolen property, including guns, musical instruments, cameras, microwave ovens and typewriters.

The suspects are Armando Aquino, 21; Manuel Guillen, 22; Howard Hyatt, 18; Sergio Lopez, 18, and Armando Moreno, 20. They were booked at the Sheriff's Department's Industry Station for investigation of burglary and are being held in lieu of $2,500 bail each.
