Janet Steen said her son, Sgt. James Hibler, sent her a text message saying he is safe.
"All it said was, ‘I'm OK. I'm on the SAR bird,' which is the search and recovery helicopter," said Steen. "So I just hope that they are all OK and that's all I know."
When FOX 4 spoke to Steen early Wednesday, she said she believed her son was one of six Marines and two Nepalese soldiers who were on a U.S. Marine Corp helicopter that disappeared during Tuesday's devastating earthquake.
The family has since learned that Hibler was on a different helicopter. He is now helping to search for the missing chopper.
"It was just such a relief to hear from him. Our prayers have been answered and I just hope they are all okay," Steen said.
Sgt. Hibler is a graduate of Arlington Martin High School. He has been in Nepal for about a week on a relief mission following Nepal's deadly April 25 earthquake that preceded the one Tuesday.
Tuesday's magnitude-7.3 quake killed at least 76 people, injured another 2,700 and caused landslides that blocked roads and slowed the delivery of relief supplies.
On April 25, a magnitude-7.8 earthquake killed more than 8,150 people and flattened entire villages, leaving hundreds of thousands homeless in the country's worst quake since 1934.
Hibler's brother, Jonathan Hibler, also served in the Marines. He's confident that those missing will be found safe.
"It's not over ‘til we find every single person," said Jonathan.
