A Kingman man was indicted Thursday by the Mohave County Grand Jury in the traffic deaths of four people in Golden Valley.
Daniel Brackney was indicted on four counts of manslaughter, two counts of aggravated assault and misdemeanor extreme DUI for having a blood alcohol level more than twice the legal limit.
Eric Ruiz, Roy Latimer, John Walker and Dan Zasadni were killed when their 15-passenger car pool van flipped over into the median along state Highway 68 on Feb.
The van, heading westbound, was struck from behind by a westbound 2000 Ford pickup driven by Brackney.
Brackney, 22, formally heard the charges during his first court appearance in Kingman Justice Court on Monday, where his bond was set at $250,000.
Brackney is expected to be arraigned next week in Mohave County Superior Court.
Brackney's criminal record consists of a 1999 felony charge for rioting.
He also has eight drug or alcohol-related misdemeanor charges out of Kingman Justice Court and two misdemeanor charges from Kingman Municipal Court, court records show.
He also has been cited for 23 civil traffic violations.
Brackney and a passenger were heading back to Kingman from Laughlin in the early morning hours of Feb.
21, according to investigators.
Brackney stopped the truck briefly then drove it back onto the highway heading westbound back toward Laughlin when the collision occurred around 6:15 near mile marker 16, where Highway 68 begins to climb toward Union Pass.
Brackney's blood alcohol level was tested four hours after the collision at 0.162.
An Arizona Department of Public Safety investigation has still not estimated Brackney's truck speed, DPS Officer Ray Butler said.
Ruiz, Latimer, Walker and Zasadni along with two other passengers were commuting from Kingman to the Mohave Generating Station power plant near Laughlin.
All six commuters were from Kingman except for Zasadni, who was from Golden Valley.
The other passengers, Robert Mansfield and Russell Pewsey, were airlifted to University Medical Center in Las Vegas.
Mansfield, 55, was treated and released while Pewsey, 38, was released from the hospital on Monday.
Brackney's passenger was also arrested for misdemeanor warrants.
Brackney and his passenger received minor cuts and bruises as a result of the crash.
