“I send this with broken hearts and tears,” Jayna Lang’s family said in an update on Sunday, December 1

The family of a Colorado woman who has been missing since she reportedly left her home to visit a local mall said they have received “no good news” about her.

Jayna Lang, 46, was last seen by her family in Littleton on Sunday, Nov. 24, the Park County Sheriff’s Office said in a news release. She reportedly told her relatives that she was going to visit the outlets in Silverthorne, ABC News affiliate Denver7 reported.

“Please be on the lookout for this vehicle and this group of women…It was headed to Summit County. She enjoyed frequenting Park County, particularly the Indian Mountain subdivision,” the Thursday, Nov. 28, police statement said.

Denver7 reported that Lang left her home in her white 2016 Toyota 4Runner with a license plate that read “JAYNA.”

In a Facebook update posted by Lang’s sister-in-law Stacy Laigo-Horvat on Sunday, December 1, the family said they had received “no good news” about Lang’s whereabouts, although she did not reveal the exact location.

“I am sending this with a broken heart 💔 and tears!!! We were notified this evening of the bad news regarding my sister-in-law Jayna 😔,” Laigo-Horvat wrote.

“We would like to express our thanks and appreciation to everyone across the country for the love and prayers during this terrible time! For all the effort and time in finding her this past week! Please remember and pray for my husband! Thank you and God bless!! 🙏🏽❤️”

Until the latest update posted by her sister-in-law on Sunday, family members had posted regular updates about their search for Lang.

Her brother, Eric Horvat, previously said he last spoke to her the day she went missing.

“We never thought she would be gone and we don’t know where, where she is,” he told Denver7. “She was supposed to go to Silverthorne on Sunday to look at the factory shops.”

Eric told the news outlet that he later received a call from Lang’s employer informing him that she did not show up for work the following Monday, Tuesday and Wednesday and no one had heard from her.

“Maybe her car is parked somewhere off the road, somewhere where anyone driving this weekend would have seen it,” he told Denver7.

“That was the last communication we had. My aunt and her talk every day. Me and her, every few days. So it’s very, very suspicious that my aunt doesn’t hear from her.”
