A Florida caregiver who was supposed to be watching over an elderly woman “not in the correct state of mind” made the senior live in filth and squalor — surrounded by spider webs, cockroaches, cats, feces, and even leaves — while allegedly neglecting her in a house with no air conditioning or working refrigerator, cops say.

Melanie Hess, 56, is charged with neglect of an elderly, disabled adult after being arrested Friday following a welfare check at her home in St. Lucie County, according to Hess’ arrest affidavit, which was obtained by Law&Crime on Tuesday.

Deputies went to Hess’ residence and found “extremely hazardous and unsanitary conditions,” according to the St. Lucie County Sheriff’s Office, with  one describing what he allegedly saw in the affidavit.

“Pulling into the driveway, the house appeared to be abandoned, and the grass yard was severely overgrown with weeds,” the deputy said. “Walking towards the home, I began to smell the strong odor of feces and urine associated with the smell of cats and other animals. I looked through a window and observed a white elderly female (victim) laying on a bed in a room. The bed was littered with leaves and appeared to have not been cleaned in a manner of time.”

According to the deputy, spider webs were “riddled throughout” the elderly care recipient’s room and the woman “appeared to be weak” and was unable to respond to questions. Hess told authorities that the home did not have working air conditioning or a working refrigerator.

“The victim could not tell me when the last time she had eaten,” the deputy said. “The clothes she was wearing were severely disheveled and appeared to have not been washed in some time,” they recounted. “Her hands and fingernails were dirty and had discoloration on them. I also observed several sores on both of the victims arms. The victim’s hair was severely knotted, and appeared to have not been washed in a long time.”

Inside the home, a “major roach infestation with 2-3 inch roaches” was allegedly found. Roach feces was scattered throughout the home, as well as cat feces and cat urine “where the victim sleeps,” the affidavit says. At least nine cats were present when cops arrived.

The elderly victim was transported to a local hospital and medically evaluated. Hess was booked at the St. Lucie County Jail and released on Saturday.
