An upstate New York father made a heartbreaking discovery
after tracking his two teen daughters' phones when they
stopped responding on Thursday.
Brian Trumble told Syracuse.com he was texting his daughters -
Hailey, 19, and Shelby, 17 - several times when they did not
return home from the Seabreeze Amusement Park in Rochester
that night.
He then decided to use the Find My Friends app to track
down their whereabouts on his phone and drove just a few
miles to the location it showed.
There, he found that his two teenage daughters died in a
fatal crash, and Cuyahoga County sheriff's deputies were
already cordoning off the area.
. . .
   And now a horrible question - was he bugging them so
   much with texts that they were distracting, CAUSED
   the crash ???
