A man is facing murder and manslaughter charges, more than one year after a crash on the Parks Highway which killed an elderly Big Lake couple.

Glen Hamilton III, 29, is charged with two counts each of second-degree murder and manslaughter, plus one count of driving under the influence.

According to police, Hamilton was drunk and speeding just before 1 p.m. on March 27, 2018, when he ran a red light on the Parks Highway near Church Road.

Investigators said his Audi hit a Toyota Corolla driven by 75-year-old Donna Swanson of Big Lake. Her husband, 77-year-old Edward Swanson, died at the scene.

Wasilla police said at the time that Donna Swanson was transported to the hospital; Hamilton is now charged with her murder.

Shawn Traini, the assistant district attorney prosecuting the case, said Monday that Hamilton's blood-alcohol content after the crash was .086, just over Alaska's legal limit for driving of .08. Traini said Donna Swanson ultimately "died from complications due to the crash." 

After the collision, troopers arrested Hamilton on an outstanding warrant for felony vehicle theft and two failures to comply with probation for assault and theft. Traini said the delay in additional charges was due to a wait for results of toxicology testing on Hamilton.

On Monday, Judge Kari Kristiansen set his bail at $50,000 plus supervision by the state Pretrial Enforcement Division.
