— A wrong telephone number held up Grady County deputies for more than half-an-hour on Thursday.

 Undersheriff Jim Weir said dispatchers were unable to pinpoint the location of an AT&T cell phone used to make a 911 call because they had a wrong number.

"Apparently, they (AT&T) had a new phone number for law enforcement and we didn't know it," Weir said. "The problem has been fixed. We have the right number now."

Because the woman who called 911 was hysterical and was begging someone to let her go, dispatchers thought she was possibly being held against her will.

Under normal circumstances, enhanced 911 systems will map a caller's location with GPS coordinates. However, because the system was unable to determine the caller's location, the dispatcher contacted the cell phone company so it could trace the phone.

"We hit AT&T to get the location and we got a wrong number,"  Weir said. "Five or six minutes later, we got a second wrong number and then a third wrong number. We lost 35 minutes trying to locate the number."

Weir was concerned about the length of time it took to pinpoint the location of the cell phone after hearing the 911 call in which a hysterical woman could be heard pleading, "Please let me go," and a man's voice responding "No, no, I can't."

Fearing it was a possible hostage situation, the dispatcher tried to call the cell phone back but got no answer.

AT&T eventually determined the call originated from a location in Caddo County, but when deputies arrived and spoke to area residents, they found nothing suspicious.

Finally, AT&T determined the phone had been purchased by an individual in Broken Arrow and notified Broken Arrow police.

By that time, more than two hours later, the man and woman heard on the 911 call were in Chickasha. The woman reportedly jumped out of her boyfriend's car and called out for help. Weir said the man then forced the woman back into the car and went around to the driver's side of the car. The woman got out of the car a second time, again calling out for help, and people in the area heard her cries and called police.

Weir said the couple has a history of domestic abuse and both are in anger management classes. Weir also said the district attorney's office will decide whether to file domestic abuse charges.
