GOLDEN GATE ESTATES, Fla. - The Collier County Sheriff's Office is investigating the drowning death of a toddler in Golden Gate Estates.  The victim, Ava Grace Slaby, was only 15 months old.
Around 8:45 Tuesday morning, 911 received a call about a "drowning" at 26th Avenue SE. According to the Collier County Sheriff's Office, when responders got to the house, they found Randi MacLeod on the floor of the master bedroom, performing CPR, and trying to save her 15-month-old baby girl, Ava Grace Slaby.

Ava was taken to the hospital, where she was pronounced dead. While the investigators have not yet released what they believe led to the baby's death, her grandmother Pamela Slaby says MacLeod told her Ava drowned in the bathtub.
Slaby says she received a frantic phone call from MacLeod Tuesday morning. MacLeod was unsure if her baby was still alive.

She said MacLeod told her she'd only left her child alone in the bathub for a very short time before finding her unresponsive.
Slaby says she's devastated to lose her grandbaby just weeks after losing her son. 24 year old Christopher Slaby, the baby's father, was killed in a car accident on Pine Ridge Road in January. Ava was also inside the car, but she was not injured.

While neighbors we spoke with say they didn't know much about MacLeod and her daughter, they offer their prayers and support.
