TROY - Investigators spent Tuesday on U.S. Highway 2 west of Libby, examining the scene of a two-vehicle accident that claimed five lives a day earlier.
The data collected, they said, will be run through accident reconstruction software, offering a computerized model of what caused Monday's tragic accident.
"We're still on the scene, gathering the information," said Montana Highway Patrol Trooper Bob Hensley. "We won't have results for a while yet."
Investigators have said it was raining hard when a westbound GMC Yukon apparently lost control and slid sideways into oncoming traffic, crossing the path of a Dodge Stratus.
All three people in the Stratus - Jack Flasche, 68; Lois Flasche, 66; and Theresa Merrit, 55, all of Troy - were killed in the wreck.
The driver of the Yukon - Sherry Thompson, 41, of Eureka - also was killed, as was her 10-year-old daughter Kendra. Her 16-year-old son Braden has been transported to Seattle's Harborview Medical Center for treatment.
Trooper Bryce Ford said the accident occurred at about 10 a.m., and closed the highway for about four hours.
