JACKSON, MO (KFVS) - Jackson's police chief says they are working two angles in the case of missing mom Jacque Waller.
James Humphreys says they are still searching for Waller, who hasn't been seen since June 1.
But, Humphreys says they are also gathering evidence as they build a case against the person responsible for her disappearance.
As we've reported, prosecutors call her estranged husband Clay Waller a suspect.
He remains in federal custody and will be sentenced next month after pleading guilty to internet threat charges.
