Who pays? I bought my Mom hearing aids ($5000). The assisted living center said they would put them in and take them out, now they're damaged.

Put them in in the morning and take them out at night, and store them in the medical drawer. My Mom, who was mentally OK when she checked into the center (which is a dementia and Alzheimer's facility) in November (its April now) has developed some weird mental issues, not diagnosed yet. She hides the hearing aids from the staff. Last, she apparently put them in her robe which they found after washing and drying the robe, and also the hearing aids. They are under warranty so it will cost $1250 to replace them (plus the $5000 I pay in cash). Who should pay the replacement cost? My Mom or the Assisted Living Center? Isn't the ALC responsible for not checking the robe's pockets?
