Dispatchers got an abandoned 911 call from the family's home around 6:40 p.m. that same day.
Dispatchers tried twice to contact people inside the home, but couldn't reach anyone.
Protocol requires that after the second failed attempt to reach someone, dispatchers should send an officer within 20 minutes.
On that day, an officer wasn't dispatched until more than an hour later.
Fayetteville police released a statement Friday evening that read in part, "it has been determined that staff didn't follow all established protocols. Appropriate disciplinary action has been taken."
According to the AP, officials refused to say how many people were punished or what actions were taken against the workers, saying it was a personnel matter.
