A 23-month-old boy died Tuesday after he was found in a small children’s pool in the back yard of a privately run day-care center in Northeast Washington, according to District police and fire officials.

D.C. police are investigating the death. The name of the toddler was not immediately made public. He would have turned 2 on June 25.

The incident occurred about 11:20 a.m. at Diane’s Child Care, run out of a rowhouse in the 300 block of 17th Street NE, three blocks north of Eastern Senior High School.

Authorities released few details of what happened. Police would only say that their initial investigation revealed the toddler fell into the pool. He was rushed to a hospital, then transferred to Children’s National Medical Center, where police said he died.

Law enforcement officials said first responders arrived at the house and found an adult performing CPR on the toddler, who had been placed on top of a patio table. Those officials said the toddler had been discovered floating facedown in the pool.

The day-care center is run by Diane E. Gallmon, according to District licensing records. She also owns the two-story rowhouse, tax records state. Gallmon declined to comment when reached by phone Tuesday afternoon.

An Internet site promoting her business says the center is open
7 a.m. to 6 p.m. and is for children ages 1 year through 4 years old, and includes children with special needs. The site says there is a playground and promotes the center as a co-op that “requires parents’ active involvement.”

Patience Peabody, spokeswoman for the D.C. Office of the State Superintendent of Education, which regulates day-care centers, said the facility’s license is up to date. It is licensed for six youngsters — two infants and four of school age, according to records.

In a statement, the superintendent’s office said its staff along with the Child and Family Services Agency is investigating, in addition to the D.C. police. “Our thoughts and prayers go out to the family of the child,” the statement says.

Pools are allowed at day-care centers in the District. The city requires adult one-to-one supervision for toddlers 36 months and under who use a pool. “A Licensee shall maintain constant and active supervision when any child is in or around water,” the regulations state.

The District also requires written permission from parents or guardians to allow children to be in water that is more than one foot deep. Pools at least four feet deep must be behind a secure fence and “inaccessible to children at all times, unless qualified adults are present.”
