SPANISH FORK -- The woman killed when her car crashed into the Spanish Fork River Friday night has been identified by Spanish Fork police. 

Springville resident Jennifer Lynn Groesbeck, 25, died when she crashed a Dodge 4-door passenger car near Arrowhead Trail and Main Street and landed upside down in the river below. Her car was found more than 13 hours later by a fisherman.

Also in the car was Groesbeck's 18-month-old daughter, Lily Groesbeck, who was found alive in the upside down car.

The infant was taken to Mountain View Hospital in Payson and later transported by helicopter to Primary Children’s Hospital in Salt Lake City. She is listed in critical condition. 

“So far, she is doing remarkably well,” said Jill Sanderson, the baby's aunt. “The doctors are hopeful at this point, but the next 48-72 hours will be critical.”

Investigators believe the vehicle struck the cement barrier on the south end of the bridge and traveled into the river, said Lt. Matt Johnson, with the Spanish Fork Police Department.

“It is unknown why the vehicle left the roadway,” Johnson said.

Friends of the family have set up a fundraiser at gofundme.com to help pay funeral expenses and the toddler's medical costs.

“She was a very compassionate caring person, she was always willing to bend over backwards for her loved ones,” Sanderson said. “She had a positive impact on a lot of people’s lives. She loved her baby with all of her heart and was thrilled to be a mother.”

An angler had been fishing in the river Saturday when he came across the crash scene near Spanish Fork Main Street and Arrowhead Trail Road shortly after noon. Officers received the call at 12:24 p.m.

Upon arrival of emergency services the vehicle was tipped on its side and that is when the 18-month-old girl, Lily Groesbeck, was discovered.

Three police officers and four firefighters were transported to Mountain View Hospital to be treated for hypothermia. The officers and firefighters have since been released.

“They absolutely saved Lily’s life and I know some of them were hospitalized,” Sanderson said. “We want to express our appreciation for them.”

Family members of the deceased reported that the mother left a residence in Salem Friday at about 10 p.m. and was traveling to her home in Springville. A resident near the accident scene said he heard something at about 10:30 p.m.

“He checked the area but did not locate anything out of the ordinary,” Johnson said.  

The Utah Highway Patrol is assisting the Spanish Fork Police Department with the investigation.
