SALT LAKE CITY (ABC4) — Elizabeth Salgado’s family is reaching out to church members.

The anniversary of Elizabeth Salgado’s disappearance is approaching. She disappeared on April 16, 2015 as she was leaving her language school in Provo. His remains were found three years later at Hobble Creek Canyon in Utah County. His killer was never found.

“How come a country that has all the technology in the world was not able to catch whoever killed my niece,” said her uncle Rosemberg Salgado.

They became frustrated with the investigation by the Utah County Sheriff’s Office. They took over the Provo police investigation.

“Why is it taking them too long to solve this murder,” said the uncle. “We know that if it was the president’s daughter, it would have been resolved by now.”

A spokesperson for the Utah County Sheriff’s Office said the case remains active and they are still getting leads, but so far it has not resulted in a suspect.

On Facebook, Elizabeth’s mother reached out to members of her daughter’s ‘YSA neighborhood of Provo’, asking ‘please support me’ and ‘who my daughter Elizabeth was related to’. i.e. who did she befriend during her brief stay in Provo? Elizabeth arrived at the end of March and moved into an apartment. His friends were limited according to his family.

His mother also targeted a person, Mackey Smith, who lived in the same apartment complex and taught him English. But, he suddenly moved away after his disappearance, according to the Salgado.

Her uncle said Elizabeth liked young Spanish-speaking white men.

“She was very excited with the Whites,” he said. “She was very impressed, like every time she saw a white man she always talked about him.”

The family hired their own private detective to help solve the case. He said he cleared him as a suspect.

“He was very helpful in coming forward and very helpful in getting the message across and we want to clear him as well,” Jason Jensen said. “According to him, he’s only hung out with her two or three times and the person we’re looking for, we suspect has hung out with her a lot more times than that.”

Jensen said a construction project was underway when Salgado went missing. Salgado was known to pass this site every day she walked to school.

“There was a report from someone working there that he said co-workers may have done something,” Jensen said. “Now this has not been verified and we would like more information on this.”

Jensen also said both Salgado uncles were cleared early in the investigation.

“(Rosemberg) was in California when she disappeared,” Jensen said. “The other was not in the area according to his phone records.”

It has been almost seven years since the family heard from Elizabeth. They only hope that justice will come to them soon.

“His family is not well, until they get a closure and find out what really happened,” Rosemberg Salgado said.

Anyone with information, especially members of the Elizabeth Church neighborhood, is urged to contact the Utah County Sheriff’s Office or Jason Jensen, the private investigator.
