Authorities are searching for two North Platte teens after they drove into the raging South Platte River.

At around 11:23 p.m., on Monday, the North Platte 911 Center received a report that a vehicle had driven into the South Platte River.

Deputies from the Lincoln County Sheriff’s Office and North Platte Fire and Rescue responded to the location, about one-half mile west of Buffalo Road on South River Road.

Deputies say some other teens were following a vehicle being driven by 17-year-old Alexis Wiezorek, when Wiezorek’s vehicle drove around some barricades and continued traveling on South River Road.

Witnesses said Wiezorek’s vehicle was traveling at a high rate of speed and drove into the river, then floated down stream.

Authorities say the witnesses tried to reach Wiezorek and her passenger, 18-year-old Noah Ramos, but were unable to.

Deputies then discovered a second accident, finding three male teenagers all injured in the roadway.

The teens, identified as 18-year-old Devan Hovden, 22-year-old Francisco Rojo and 18-year-old Garret Axtel, said they had driven into the area to look for their friends who had driven into the river.

They advised that they were traveling at around 50 mph, and could not see that the road had washed out.  They said their vehicle then enter the river.

All three were transported to Great Plains Health with non-life threatening injuries.

Deputies say the North Platte Police Department, Nebraska State Patrol, Lincoln County Emergency Management and Midwest Air conducted an extensive search of the area, but have been unable to locate Wiezorek, Ramos or either vehicle.

Officials ask that all non-emergency personnel please stay away from the South Platte River.

Citizens who travel on closed roads will be arrested for trespassing.

Deputies say drugs and alcohol may be a factor in the accident.

The investigation is ongoing.
