EAST LANSDOWNE, Pa. — Authorities in a suburban Philadelphia community are searching for a missing 40-year-old mother of two.

Police in East Lansdowne say Melissa Melba Brown was reported missing Tuesday by her children, ages 9 and 11. Police chief John Zimath says the children had been living by themselves since Friday.

Zimath tells the Delaware County Daily Times that right now it's being treated as a missing person case. The children have been turned over to the county's Children and Youth Services.

The chief says the main concern is that Brown is OK.
