Head of academy's lawyers: He's 'heartbroken,' cooperating with police

Attorneys representing Yuval Kahan, the head of the pre-military academy whose trip for prospective students resulted in the deaths of 10 teenagers, say he is “heartbroken” by the incident and is cooperating with investigators.

Kahan has been in police custody since early Friday. He is suspected of negligent homicide for failing to heed the weather warnings.
