Pregnant mother killed in Los Angeles bike crash along with unborn daughter

A devastating tragedy has struck a young family in Los Angeles after a pregnant mother was allegedly killed while cycling with her husband and two sons.

Regan Cole-Graham, 36, was seven months pregnant when she was struck by a vehicle on Saturday.

In a heartbreaking update shared via a GoFundMe page, the family confirmed that her baby girl, who was delivered and rushed to the NICU at UCLA Children's Hospital, has also passed away.

The family was enjoying a weekend bike ride together when the collision occurred, an event that has left her husband, Matt Graham, and their two young boys to navigate an unimaginable loss.

"Regan was a loving & devoted wife, a fierce & joyful mother, a hilarious & loyal sister, and a beautiful, fiery daughter," her family wrote in a moving tribute.

Images shared by loved ones show a happy, vibrant woman smiling on the beach and celebrating her pregnancy.

The wider community and friends, including journalist Chris Cillizza, have rallied to support the grieving family, raising more than $100,000 in just a few days.

Cillizza urged others to help his friend "who has had his entire life change in the space of the last 2 days."

While the LAPD continues to investigate the details of the crash, the outpouring of grief and financial support highlights the profound impact Regan had on those around her.

The funds are intended to cover funeral costs and provide for the future of her two surviving sons.
