Two people believed to be illegal border crossers were shot dead near
Red
Rock Wednesday afternoon after someone opened fire on a group gathered
around a stock pond, a Pinal County Sheriff's spokesman said.

Sheriff's officials said late Wednesday that a search would resume this
morning to try to find the others in the group. Authorities are
concerned
that others in the group who ran from the stock pond may have been
wounded
in the shooting and are still out in the desert.

Mike Minter, a sheriff's spokesman, said at least 12 people believed to
be
illegal entrants were at the stock pond in a fairly remote desert area
about four miles from Interstate 10. Red Rock is just north of the Pima
County line.

One person in the group said a vehicle approached the stock pond
between
noon and 1 p.m. and someone in the vehicle opened fire.

The group scattered immediately, but one person eventually made it to a
phone to call for help after 4 p.m., Minter said.

Pinal deputies responded to the area and found the two dead but could
not
find any others in the group except for the person who had called them,
Minter said.

Investigators continued looking for other victims of the attack late
into
the night with the assistance of a Department of Public Safety
helicopter
and dogs.

It is unknown if anybody else in the group was wounded or killed,
Minter said.

It wasn't known late Tuesday how many people were in the vehicle or
what
kind of firearm was used in the shooting
