MILWAUKEE (WTAQ) - A 10-year-old girl killed in a traffic crash in Milwaukee was identified Tuesday as Brianna Johnson.

A medical examiner's report said the girl's mother was distracted by Brianna's 5-year-old sister who was asking about a toy she got for Christmas.

When the mother took her eyes off the road, the car slid under a parked semi-truck.

The crash happened on Monday. The three were heading home from their father's house at the time.

Officials said the 5-year-old was critically injured, and alcohol might have been a factor in the crash. Police said the driver was arrested and later released, pending possible charges.
