California congressman's 3 grandchildren reported missing

Authorities were investigating the disappearance Monday of three grandchildren of Southern California Rep. Gary Miller.

The children were reported missing at about 1:30 p.m Monday from their Diamond Bar residence east of Los Angeles, Los Angeles County sheriff's officials said.

Investigators were looking into whether the children were taken by their "non-custodial mother," said sheriff's spokeswoman Deputy Aura Sierra, referring to a parent without custody rights.

The children's parents are divorced and appeared to be in a custody battle, the San Gabriel Valley Tribune reported on it Web site.

Messages left with Miller's local offices were not immediately returned Monday night.
Miller represents the 42nd Congressional District, which includes the communities of Diamond Bar, Brea, Chino and Chino Hills.
