Moments before a suspected drunk-driving crash that left three people dead, the Kenosha County Sheriff’s Department received a 911 call about a white pickup driving erratically at high speed on Highway 50.

Almost immediately after that 911 call, the white GMC pickup crashed at high speed into a Jeep SUV in the eastbound lanes of the 21600 block of Highway 50 at 6:45 p.m. Friday.

The Jeep — with four people inside — flipped and came to rest upside down in a marshy area down a hill on the south side of the road.

The pickup continued east before running off the road about 100 yards away from the Jeep, crashing through a fence and into a wooded area on private property.

One person in the Jeep died at the scene. On Saturday, Sgt. Tony Gonzalez of the Kenosha Sheriff’s Department reported that two more people who had been in the Jeep died at the hospital.

Gonzalez said all three victims were adults and members of the same family. The identities of the people killed in the crash will not be released until Monday at the request of the family to give them time to notify relatives, he said.

He said the fourth person who was in the Jeep remains hospitalized.

The driver of the pickup also remains hospitalized in stable condition. Gonzalez said the department is also not releasing any information on that driver, but said he expects him to face criminal charges.

Salem Lakes Fire Chief Mike Slover said the scene was “chaotic” because of the distance between the two vehicles and the difficulty rescuers had getting to them because of the sites.

He said the Jeep had come to rest upside down in a cattails at the bottom of a steep slope.

The pickup was also inaccessible to rescue vehicles, and Slover said rescuers had to carry the driver from the pickup and across a creek to reach an ambulance.

Slover said rescuers called for Flight for Life helicopters to take patients to the Level I trauma center at Froedtert Hospital in Wauwatosa, but both both helicopters were on the scene of other incidents and were unavailable.

Slover said a Flight for Life ground transport ambulance took one patient directly to Froedtert. The three others were taken to local hospitals, then transported to Froedtert.

Although the accident is still under investigation, the sheriff’s department said alcohol and speed is believed to be a factor.
