GLENVIEW, Ill. (CBS) — A little boy drowned during a visit to a public pool in Glenview last Friday, and his family has since been trying to learn exactly what happened — reportedly with little success.

As WBBM Newsradio’s Bob Conway reports, Vicente Cardenas, 4, was at the Glenview Park District’s Roosevelt Pool, 2239 Fir St., at about 2:30 p.m. this past Friday.

He was among 19 children and eight adults at the pool from the Wesley Child Care Center summer camp, the Chicago Tribune reported.

Vicente’s uncle, Val Gurvits, tells the Tribune it has been impossible to get information about the exact circumstances of the child’s drowning in five feet of water either from police, Glenview officials or the day care center’s director.

Gurvits tells the Tribune that witnesses told him Vicente’s body was first discovered by other children, and then pulled from the water by a lifeguard.

Gurvits, an attorney who lives in Boston, tells the newspaper that negligence was clearly involved on many levels.

He tells the Tribune “that something stupid, preventable (and) avoidable happened because someone didn’t think through the field trip.”

Witness Kelly Nicioli told CBS 2’s Mike Puccinelli last week that lifeguards tried for several minutes to revive the child before paramedics arrived.

“It was disturbing, sickening, to see this happening to a little kid,” said Nicioli, 14, who was having a birthday party at the pool.

Vicente was pronounced dead at Glenbrook Hospital just over an hour after he was found unresponsive in the pool.

Wednesday would have been Vicente’s fifth birthday.
