Did you hear about this? There's not much info but it's breaking my heart.

68-year-old Marla Langley was walking down the sidewalk pushing a stroller with her 2.5-year-old grandson in it when an impaired driver in an SUV swerved and hit her.

The 34-year-old driver swerved to avoid slamming into a bus and is believed to have been under the influence of drugs.

Langley succeeded in pushing the stroller out of the way but was struck and killed.

Upon learning of the situation the boy's mother credited Langley with saving her son's life and believes she sacrificed herself to get the stroller clear of the SUV. Heartbreaking.
