Melissa Joan Hart says she helped kids flee Covenant School in Nashville shooting

When children were fleeing Covenant School Monday as a shooter roamed the hallways, actress Melissa Joan Hart and her husband happened to be driving by.

She was on her way to her children's school, near the Covenant School, for a parent-teacher conference, she said in an Instagram video posted Tuesday.

"We helped a class of kindergarteners cross a busy highway," she said, getting choked up. "They were climbing out of the woods. They were trying to escape the shooter situation at their school. So we helped all these tiny little, little kids cross the road and get their teachers over there and we helped a mom reunite with her children."

Hart called for "prayers today, action tomorrow," in the caption of her video.

Three children — Evelyn Dieckhaus, Hallie Scruggs and William Kinney — along with head master Katherine Koonce, substitute teacher Cynthia Peak and custodian Mike Hill were killed when 28-year-old Audrey Hale opened fire inside the building about 10:13 a.m.

Metro Nashville police have said some children hid in the wood line around the school while others sheltered in classrooms. There were children on the playground when Hale pulled into the parking lot of the school before 10 a.m., according to surveillance footage released by police.

After Hale was killed by officers Rex Engelbert and Michael Collazo, students were evacuated in lines. Some held onto the shoulders of the student in front of them and kept their heads down. Most were put inside Metro Nashville Public Schools busses and shepherded to Woodmont Baptist Church where a reunification site was set up.

Hart, best known as the lead characters in 1990s shows "Sabrina the Teenage Witch" and "Clarissa Explains It All," said she and her family moved from Connecticut where her children attended school near Sandy Hook.

"So this is our second experience with a school shooting with our kids being in close proximity," she said in the Instagram video. "Luckily we are all OK …Luckily our kids weren't in today."

Hart ended the video at a loss for words.

"I just don't know what to say anymore. It is just– enough is enough and just pray. Pray for the families," she said.

As news of the shooting spread, many celebrities, including Nashville residents Shawn Johnson, Jana Kramer, Mickey Guyton, Lauren Daigle and more, spoke out about the attack which marks the 89th shooting on school grounds this year, according to the K-12 School Shooting Database.
