AURORA, Colo. – The Aurora Police Department on Sunday once again pleaded for the public’s help to provide any clues that may lead to the whereabouts of Lashaya Stine, who disappeared without a trace exactly two years ago.

“Today, our hearts and sincerest thoughts are with Lashaya Stine and her family,” the department said in a Facebook post marking the second-year anniversary of her disappearance.

Stine, now 18-years-old, was last seen at around 2:30 a.m. on July 15, 2016, in the area of East Montview Boulevard and Peoria Street in northwestern Aurora.

“We refuse to give up,” the police department said, adding the investigation into finding Stine still remains open and detectives still follow up on every single lead that is brought to their attention.

The last workable lead regarding Stine’s disappearance was a video police released in August of 2016. In it, Stine can be seen walking down the street by herself.

Speaking to Denver7 in 2017, Stine’s family said the teen was eager to begin a potential summer job opportunity before she went missing.

“We believe that there is someone out there with information about Lashaya's whereabouts,” the department wrote on Facebook. “The Aurora Police Department and Lashaya's family are pleading that if anybody has information about Lashaya's disappearance, please contact the police department immediately.”

Stine is 5-foot-6-inches tall and was last known to weigh 150 pounds. She has long black hair, brown eyes and a quarter-sized, round scar on her chest. Police said she typically wears a silver watch on her left wrist.

If you have any information about Stine, you are asked to call the Aurora Crimes Against Children Tip-Line at (303) 739-6164. If you wish to submit an anonymous tip, you can do so by calling Crime Stoppers at (720) 913-7867.
