(Tacoma, WA) - A dispatcher who took a 911 call from a social worker just before Josh Powell killed his children and himself in a fiery inferno has been reprimanded.

The letter of reprimand was given to dispatcher David Lovrak, who waited nearly seven minutes before sending deputies to respond to the call on February 5.

The letter said some 22 minutes passed from the first 911 call to the time first responders arrived at the home, which by then was already in flames.

Officials said the letter of reprimand is the only punishment Lovrak will receive.

According to the letter, a supervisor said Lovrak violated four policies in the manner he handled the call from a social worker who dropped the boys off at the house in Graham - then watched it go up in flames.

During that call, the social worker tired to explain that Powell had opened the door to the home, let the boys inside, but then locked the door before she could get in.

She also warned the dispatcher she smelled gasoline inside the home.

In a recording of the 911 call, the social worker can be heard asking, "OK, how long will it be?"

The dispatcher then says, "I don't know, ma'am. We have to respond to emergency life-threatening situations first. The first available deputy ...."

The social worker replies, "Well, this could be life-threatening."

The dispatcher admitted he made mistakes and should have handled that 911 call better, according to the letter of reprimand.

It's also the fourth time Lovrak's been in trouble on the job, those included a reprimand for tardiness.

In this case, however, Lovrak says he just didn't know who Josh Powell was, or that he was a person of interest in his wife's 2009 Utah disappearance and had lost custody of his two sons.

The written reprimand - obtained via a public records request by the Salt Lake Tribune - will be placed in Lovrak's personnel file.
