Police investigating the abuse of a senile elderly woman and her mentally disabled son found a vermin-infested apartment that made one officer so sick he needed hospital treatment twice.

Lalane Brown, 76, was covered with worms, lice, maggots and excrement when her son, Dwight Brown, brought her to New York University Medical Center on Saturday. She also was extensively scarred with marks from a stun gun. Mentally disabled George Brown appeared to be in the same physical condition as his mother.Dwight Brown, 46, was arrested and charged with two counts of neglect of elderly or disabled persons, Newark police detective Rocco Malanga said.
