GLADSTONE, Mo. - William Mashburn says a quicker response could have saved his father's life.
His father, Kevin Mashburn, was killed Wednesday morning while working the overnight shift for AT&T.
According to court documents, the 58-year-old father of four instant messaged his dispatchers from a computer in his truck requesting help after he was brutally attacked with a pry bar. The documents revealed that the AT&T dispatchers did not respond to Mashburn's call for help for 19 minutes.
"To know that that he was alone and injured, probably scared and begging for help and gets no response for so long, it's difficult to imagine," William said. "If someone could have been there while he was trying to reach out and get that help, I can only assume that it probably would have worked out."
Bryan J. Middlemas, 35, was charged with first-degree murder in Mashburn's death. He pleaded not guilty to the charge in Clay County court on Monday.
First responders did not find Mashburn until 50 minutes after his first instant message to dispatchers, according to court documents.
University of Kansas Hospital trauma surgeon Dr. Charlie Richart said the first hour after a trauma injury is the patient's most critical. He says it's referred to as "the golden hour," and getting medical attention within that hour can mean the difference between life and death.
"The importance is that we get to the patient, we stop bleeding, we resuscitate the patient, we reestablish the flow of oxygen to the critical organs," Richart said. "The quicker you do, the less damage that there is and there's more likelihood of a better outcome."
AT&T, which offered a $100,000 reward for tips in Mashburn's death, has not release any explanation for the delayed response because the investigation is still ongoing.
