The Minnesota State Patrol says a 6-year-old girl wandered into freeway traffic near Minneapolis, where she was struck and killed by an SUV.

State Patrol Lt. Eric Roeske says Kallie N. Palmer had been playing at a friend's house Friday about 7:15 p.m.

He says it's not clear what happened after that. Investigators are still trying to piece together the circumstances that led her onto Interstate 35W in Burnsville, about 20 miles south of Minneapolis.

He says the home's yard is encircled by a chain-link fence that would be about waist-high on an adult. He says Kallie may have climbed over the fence.

Roeske says the whole situation was "pretty tragic."
