Alaska State Troopers have identified an ejected Wasilla driver who was seriously injured in the rollover of a pickup on Knik-Goose Bay Road Monday evening, which remains under investigation.

According to a Tuesday AST dispatch, 49-year-old Todd N. Robbins was at the wheel of the pickup, which crashed at about 8:30 p.m. near Mile 5.5 of the road in the vicinity of its intersection with Shady Lane. Troopers learned after the single-vehicle crash that Robbins, the pickup’s sole occupant, had been driving erratically beforehand.

“Investigation found a 2000 Chevrolet truck left the roadway, drove down the embankment, and rolled,” troopers wrote. “Robbins was transported to the Mat-Su Regional Medical Center with non-life-threatening injuries.”

In an email to Channel 2, AST spokesperson Megan Peters says troopers haven’t yet determined whether drugs or alcohol were factors in the crash. Further details on the nature of Robbins’ erratic driving, or whether he ran any other drivers off the road, weren’t available Tuesday night.

Mat-Su Regional officials didn’t immediately respond to a query Tuesday night on Robbins’ condition, and Peters says troopers haven’t received any further word on his status Tuesday.

Troopers say the pickup was a total loss.
