BUFFALO, N.Y. -- They are images no father want to see.

"I see my child under the water for a long period of time and then he starts floating to the top like a hollow log," Larry Watkins said.

His 13-year-old son was eventually pulled from the Waterfront Elementary school pool on Tuesday afternoon.

In the aftermath of the near-drowning, the principal at Waterfront has canceled pool activities indefinitely.

"I think it's a terribly unfortunate circumstance," Buffalo Public School Board President Jim Sampson said. "I think the principal did the wise thing of suspending activity until we can determine what happened. We have a child who almost drowned and whatever happened that led to that, we've got to understand that."

The district is currently investigating what lead to the near-drowning. A spokesperson said two lifeguards were on duty and the student did not need CPR.

"Based on the information the principal gave me, they reacted within the time frame of emergencies and they followed the procedures," Board Member Mary Ruth Kapsiak said.

"Our sympathy goes out to the family and everyone that was involved," Jim Sampson said.

But Watkins said the district did not show similar concern Tuesday when doctors put his son in an induced coma after he was rushed to Women and Children's Hospital.

"You signed a permission slip for your child to go on a field trip and the people that you give guardianship over your child for that field trip, drop the ball and act like they just don't care," Watkins said.

After watching footage of the incident, Watkins isn't sure they acted appropriately in real time either.

"The people that were watching him and the lifeguards in the pools," he said. "I would like to know what were they doing."

For their part, board members said they're not ignoring the issue.

"I have spent some time today at Waterfront and I do need to look at the footage of what happened," Kapsiak said.

"I think there's a lot of questions that have to be asked and we have to ask them for the entire district, not just one pool," Sampson said.
