The emotionally charged rescue of a Layton toddler who nearly drowned in his bathtub two years ago is featured on national television in next Tuesday's "Rescue 911."

On the afternoon of Aug. 30, 1988, Davis County sheriff's dispatcher Karen Wright answered a call on the county's 911 emergency system. On the other end of the line was a frantic and distraught Lori Chapman.She had put her son, Chase, then 8 months old, into the bathtub and went to answer the telephone, talking briefly. When she returned, she found him floating face down in the water, turning blue.

Wright immediately dispatched paramedic and ambulance units, then began calming Chapman down and started talking her through emergency cardiopulmonary resuscitation measures.

In the few minutes it took for paramedics to arrive, Chapman had Chase breathing again. Chase's unhappy crying can be heard clearly in the background of the original tape as paramedics pull up in front of the house.

A year later, Chase inaugurated the county's new, enhanced dispatch system in a ceremony at the sheriff's department, punching out the 9-1-1 numbers on a telephone equipped with special oversize numbers.

Film crews from the "Rescue 911" program, narrated by "Star Trek" star William Shatner, filmed a re-enactment of the rescue last December, spending about a week at the sheriff's department headquarters in Farmington and the Layton home of the Chapmans.

The segment, which uses many of the dispatchers, paramedics, and others actually involved in the original incident, airs at 8 p.m. Tuesday, April 9, on KSL-TV, Channel 5.

The segment uses the actual tape made of the call and features Lori and Chase Chapman, Wright, and paramedic Sgt. Dave Fluckiger. His partner at the time, Russ Whitney, is no longer with the sheriff's department and is portrayed by another paramedic, Alan Pratt.
