Pendleton, California -
(KPNX) There are new details out about the attack on California electrical transformers last April.
The incident happened one day after the Boston bombings which is why there's been little reporting on the incident.
Now authorities say the damage is the work of a sniper and they are treating the shootings an act of terror.
Officials say this attack on a California power station was different.
"It appears to be very well organized and very well planned," said Steve Harrison of the Arizona Department of Public Safety.
In just two hours in the middle of an April night last year, a military style sniper attack took out 17 transformers powering the Silicon Valley.
Arizona Department of Public Safety Captain Steve Harrison is deputy director of Arizona's counter terrorism operations at the Actic Fusion Center.
He and others agree authorities simply don't know anything about the shooters' motives.
Security expert Norman Beasley says power stations can easy pickings for bad guys because they are out in the open.
"That makes them sitting ducks for any kind of attack be it terrorist attack, be it criminal," said Beasley.
Dan Froetscher oversees all of Arizona Public Service power facilities and lines.
He said the attack was no different from any other disruption.
"Not any different than weather equipment failure," Froetscher said.
Froetscher was reluctant to say what A.P.S. did to beef up security out of fear of possible copycats.
The attack did not turn off the lights in the Silicon Valley.
The utility managed to reroute the power.
The FBI continues to investigate the attack, but no arrests have been made.
