Milwaukee road rage shooting, mother dead; 18-year-old in custody

We are learning more about the woman police say was shot and killed during a road rage incident on Monday.

The witness told police Hernandez-Lopez yelled at Ruiz, which Ruiz said happened in Spanish. The witness said Ruiz replied, yelling, "[Expletive]! I'll call immigration on you," while flashing a gun.

A short time later, court filings said the two continued following each other's cars before Hernandez-Lopez "brake-checked" Ruiz's car, causing contact.

When Hernandez-Lopez pulled a U-turn to drive away, on Lapham, police said Ruiz shot at Hernandez-Lopez's car, hitting her in the neck. The witness told police she saw Hernandez-Lopez get hit and assumed she had died.

Police said they recovered a gun from the vehicle that brought Ruiz to Milwaukee Police District 2 when she turned herself in. The ballistics on that gun matched the casings recovered from the scene.

Additionally, when officers received permission to search Ruiz's car, they said they found four additional shell casings with matching ballistics.

According to court filings, Ruiz wrote an apology letter to Hernandez-Lopez's family, in which she said she'd been having a bad day and had fought with her mother.

Ruiz has not yet made her initial appearance in court.
