Sheriff Tom Dart said the goal of the project is to bring attention to their stories, with an initial focus on missing women.
Martin's three daughters have been working closely with the sheriff's office as part of the project.
"We urge anyone with information to please come forward," said Latrina Martin. "Our mom is loved and missed by all of us."
Dart says most cases involving women are often overlooked and he hopes by sharing their stories, new information will be brought to family and friends who have been seeking answers for a long time.
"These are incredibly challenging cases to solve and behind each of them are family and friends just left devastated and worrying with no answers," Dart said in a statement. "The families of these missing women deserve the public’s attention and help in trying to find answers."
Yasmine Acree has been missing for 13 years. Some family members believe the honor student, who was 15 at the time, was abducted after leaving her West Side home.
Her cousin, Pastor Ira Acree, said the hardest part is not knowing what happened.
"We’ve heard rumors in Cook County that some gentleman knows something about Yasmine and he participated in her death," said Acree.
The project covers everyone that has been reported missing in Cook County since 1930, which includes about 170 people.
Each of the cases will be featured on a new Missing Persons website as well as the sheriff's office's social media channels to help generate tips.
