An Arizona man has been charged with murder following a high-speed crash in Tucson that killed a 3-year-old girl and injured her pregnant mother, according to authorities.

The collision allegedly involved street racers and was severe enough to split the victims' vehicle in half. The 3-year-old girl, identified as Anna, was killed in the crash while her pregnant mother sustained injuries.

The incident has prompted murder charges against the alleged street racer, though specific details about the circumstances leading to the crash have not been fully disclosed by authorities.

A fundraising campaign established for the family described Anna as "a bright, joyful, and loving little girl who brought so much happiness to everyone around her."

The case highlights ongoing concerns about illegal street racing and its deadly consequences for innocent motorists and pedestrians. Authorities continue to investigate the incident as the legal proceedings move forward against the charged individual.
