For the third time in as many weeks, an exhaustive search of the Anoka County-Blaine Airport ended Tuesday with no sign of the man charged with killing his onetime romantic and business partner outside an Arden Hills gas station.
The search, involving dozens of officers in tactical gear hunting on foot and from the air, was prompted by an early-morning sighting of a man near the airport fence who may have been Lyle "Ty" Hoffman, according to Blaine Police Chief Chris Olson.
The tip came on the heels of a bank robbery Sunday in Blaine committed by a man whose features on video footage strongly resemble Hoffman's.
Also Tuesday morning, officers searched a school bus yard near the airport after police found evidence that someone tried to break into the lot, but found nothing.
At an early-evening news conference after the search ended, Olson said officers "checked all areas that we thought we had to check" after the morning sighting. An officer who spotted the man before daybreak alerted others and a perimeter was quickly set up, but a day of searching within it turned up nothing, Olson said.
For much of the day, all gates leading into the airport were blocked by squad cars from the Blaine Police Department and the Ramsey County Sheriff's Office. An ambulance was also on the scene. Authorities also closed the exit from Hwy. 10 to 93rd Lane, which leads to the airport. The roads were reopened in late afternoon.
The search included a sweep through wooded areas on the grounds as a State Patrol helicopter hovered overhead, with an officer poised at the open door, scanning below while holding a rifle.
Olson said that law enforcement will continue to respond to any tips about Hoffman's whereabouts until he is found.
