"emergency locator"

I got this email forwarded through a friend. Does anyone heard of it? If
it's true it could be very useful. PeterK

"You may remember that a young woman was recently abducted from a Target
parking lot in Overland Park, a suburb of Kansas City. Her body was
discovered many miles away in Missouri. They were able to locate her by the
sequence of cell phone towers that picked up her cell phone location. She
had not attempted to dial out, but when her family was trying to call her
the towers could sense her phone. Sadly, the authorities were not able to
reach her in time. However, they were able to locate her body which was in
an area where they never would have searched without the cell phone tower
information.

Below is information from my daughter-in-law who lives in Kansas City . The
cell phone "locator" can be either set on "E911" in which case you must dial
out to be located, or it can be set to be on all the time. I called my cell
phone company and was assured there is no negative consequence (like higher
battery use) from having it on all the time. With it on all the time you can
be located by emergency services through the police if you fail to respond
(sick, injured or worse).

I found that on my phone "location" was not on. I turned it on so my phone
can be traced. See below for more info that was sent to me by someone here
at work:

ALL cell phones have this feature. It's called Location. It's under the
Settings tool (on my phone it's under Settings, System, Location). Once you
turn this on, THEN your phone is traceable (select "Location On" instead of
"E911 Only"). To stay safe, everyone needs to check their phone and turn
this on!!! "
