A mother and daughter were killed when an 800-pound boulder fell off of a truck and hit their car.

Karen Christiansen, 67, and daughter Jena Christiansen, 32, died in the freak incident on Rich Valley Road in Rosemount on Monday.

The pair, who are both from Shoreview, died from blunt force head trauma "due to a motor vehicle mishap," according to the Hennepin County Medical Examiner's Office.

They were traveling north on Rich Valley Road at 4:50 p.m. when the boulder came loose from a commercial vehicle traveling the opposite direction, falling onto their Toyota Avalon.

Rosemount police are now investigating the incident, saying they have identified the company vehicle and the driver and will now seek to figure out how boulder came to fall from the truck.

Jena Christiansen was a general manager of several Red Lobster restaurants, according to her boyfriend Ryan Kilian, who released a statement to WCCO on Wednesday evening.

"She is the most amazing person I have ever met," he wrote. "She was so smart and beautiful. She made me the man I am today I would be nothing without her."
