A Tennessee woman has died three years after giving birth to her son while in a coma.

Sharista Giles’ family confirmed in a Facebook post that she had passed away Monday, almost four years after being severely injured in a car accident.

In 2014, Giles was returning to her Sweetwater, TN, home with friends from a concert in Nashville when the driver of the car hit a guardrail, according to WATE 6.

While her friends walked away from the crash, Giles was badly injured and unresponsive.

At the time, she was four months pregnant with a son, Leighton. Despite his mom being in a coma, Baby L – as his family dubbed him – was successfully delivered by doctors.

Lighton, who turned 3 in January, was born prematurely and weighed two pounds upon birth, according to Fox News.

Following her son’s birth, Giles remained unresponsive. However, in April 2015, Giles woke from her coma when she fluttered her eyes open.

According to her family, Giles slowly regained the ability to open and close her hands and did say a few words.

In December, Giles suffered from “double pneumonia” and spent time in the ICU, according to a Facebook post by her family.

They asked everyone for prayers in March, although details of what Giles was ailing from were not revealed.
