Two people in Carlton County died in separate ATV crashes over the holiday weekend.

The Carlton County Sheriff’s office reported Trisha Jean Lanthier, 47, of Proctor "received multiple injuries" after losing control of her ATV in Barnum Township and rolling it at about 11:40 a.m. Saturday, July 4, at the intersection of County Roads 139 and 6. She was transported by medical helicopter to Essentia Health-St. Mary's Medical Center in Duluth, where she later died.

Lanthier, driving the ATV south on County Road 139, likely didn't see the intersection because of the dust created by the other ATVs in her group, the sheriff's office said.

"Due to the dry conditions the group of ATVs had created a large amount of dust on the gravel road. It is believed that due to limited visibility from the dust, the victim did not see the approaching intersection," the sheriff's office said in a news release. "When the female victim attempted to stop her ATV, she lost control and the ATV rolled over on top of her."

Lanthier was wearing a helmet at the time of the crash and alcohol is not thought to be a factor.

Later that day, the sheriff's office responded to a 911 call about a crash shortly after 8:30 p.m.

Seamus Patrick Flynn, 48, of Minneapolis had been driving an ATV on property off Golf Course Road in Holyoke Township. The sheriff's office reported that while no one witnessed the crash, it appeared the ATV was traveling down a hill when it rolled on top of the man, pinning him underneath.

Lifesaving measures were attempted on Flynn, however, he was pronounced dead at the scene. He is reported to not have been wearing a helmet and alcohol is not believed to be a factor in the crash.
