Salt Lake City police on Friday afternoon were searching a portion of the Jordan River for evidence linked to a Salt Lake City woman who vanished nearly 12 years ago.

Aletha Jo Williams was 25 years old and 6 months pregnant when she last was seen March 6, 2002.

Police — who met with news media near 2590 S. 1160 West — said they expected to be in the area for several hours doing a ground and aerial search for evidence in William's disappearance.

Det. Cody Lougy said Friday that several credible tips led them to reopen the case and focus on the Jordan River, but police have not described the nature of the tips.

Police said divers searched the river earlier this month, but didn't find anything.

Friends and acquaintances of Williams are asked to contact police.

Williams last was seen near 1700 South and West Temple, where she dropped off her belongings at a relative's house and said she would return. There was no further word as to Williams' whereabouts and police on Wednesday had no information as to the outcome of her pregnancy.

Her family reported her disappearance in May 2002.

Williams is black and 5 feet 2 to 5 feet 4 inches tall. When she disappeared she weighed 140 pounds, had pierced ears and a pierced tongue, and the name "Shawn" was tattooed on her wrist.
