CASSELBERRY, Fla. — In January, 1-year-old Joey Cosmillo wandered into the back yard and fell into the family pool. When his mother hauled him out, he wasn't breathing. Rescuers were able to bring him back to life, but he suffered severe brain damage and cannot walk, talk or even swallow.

Now, his family faces another burden: One of the rescuers, Casselberry Police Sgt. Andrea Eichhorn, is suing, alleging the family left a puddle of water on the floor that afternoon, causing her to slip and fall.

The boy's grandparents, named in the suit, are mystified and angry.

"The loss we've suffered, and she's seeking money?" said Richard Cosmillo, 69, the boy's grandfather. "Of course there's going to be water in the house. He was sopping wet when we brought him in."

Eichhorn last week sued Richard Cosmillo; his wife, Maggie Cosmillo; and the boy's mother, Angela Cosmillo, accusing them of negligence. They were careless, according to the suit, and allowed the home they shared to become unsafe.

As a consequence, Eichhorn broke her knee, which kept her off the job for two months, according to police Chief John Pavlis.

Joey now lives in a nursing home five miles away, where he gets 24-hour care. He breathes through one tube. He's fed through another.

"He doesn't have any abilities — any," his grandmother said."He can't sit. He can't swallow. He can't eat. We're not even sure he can see."

She and Richard Cosmillo are the boy's legal guardians. For the first two months after the accident, she remained at his bedside, never once going home.

She has now gone back to work at a furniture store, and her husband keeps watch on the boy. He visits every day.

"This thing," Maggie Cosmillo said, "has destroyed our lives forever."

The baby's mother was the only one home Jan. 9, when the boy slipped out of the house and wound up in the pool, according to a police report.

She plunged in and dragged him out, carrying him inside, down a hallway and into a bedroom. She also called 911.

Eichhorn arrived a few minutes later. As she stepped into the room where rescuers were working on the boy, she slipped and went down on one knee, then stood back up, according to Richard Cosmillo.

Later that day, she went to an emergency care center and eventually to an orthopedist, according to her attorney, David Heil.

While she was on medical leave, Pavlis said, the city's insurer paid her medical bills and provided disability checks.
