MILWAUKEE (CBS 58) -- A fatal crash closed all northbound lanes of I-41/894 near National Avenue Friday morning, Dec. 23. 

According to the Milwaukee County Sheriff's Office, just after 9 a.m., a multiple-vehicle crash occurred near National Avenue. The drivers of two vehicles involved pulled over. A third vehicle pulled over and that driver exited his vehicle apparently to check on the wellbeing of the drivers who had been involved in the crash. 

The sheriff's office says one of the drivers involved in the crash, a woman, exited their vehicle, too.

Moments later, MCSO says a fourth vehicle came along and struck the two drivers that exited their vehicles. 

The apparent good Samaritan was injured and taken to an area hospital in stable condition. The female victim was killed. 

Both crashed remain under investigation.
