PUYALLUP, Wash. — The 29-year-old woman driving at the time of a fatal crash in Puyallup that killed four children in January had a blood-alcohol level of .201%, well above the state's legal limit of 0.08%.
Kiarra Monaghan was driving at speeds in excess of 100 miles per hour at the time of the crash on state Route 512 on Jan. 14, according to information from Washington State Patrol.
Though temperatures were low, there was no sign of ice or conditions that would have factored into the crash. Additionally, there was no evidence of braking, according to state patrol.
"Rather, this seems to be a case of an extremely impaired person unaware of their speed or peril and so far behind in their road perception and response time that the impact was sudden and simply not survivable for anyone in the vehicle," State Patrol Communications Director Chris Loftis wrote to KING 5.
According to State Patrol, Monaghan was driving a Ford Flex eastbound on SR 512 when she drove off the road and struck a support pillar for an overpass. One person was ejected. The vehicle caught fire. The four other people inside did not escape.
Monaghan was killed, along with: Amiyah Eutimio, 3; Amiira Little, 11; TaeShon Manuel, 11; Noah Monaghan, 12.
Monaghan is believed to have posted on social media in the hours before the crash. Those posts became part of State Patrol's investigation. The videos, posted on Facebook Live, show Monaghan with children and friends along her side early that morning where she appears to be drinking alcohol. Three hours later, investigators believe she was behind the wheel.
According to Loftis, prosecutors are not able to bring criminal charges in relation to people "allowing" Monaghan to drive.
