Connecticut State Police have set up spot checks near the Eastern Connecticut State University campus Saturday.
Police hope to zero in on new evidence and get more information about the whereabouts of Alyssiah Marie Wiley, a 20-year-old from West Haven, who was last heard from on April 20.
Wiley, a sophomore at ECSU, is studying psychology and biology with with the intention to get ready for medical school to get a doctorate in psychology, said Alyssiah's mother Corrinna Martin.
She was last seen at a Diary Queen in Willimantic.
State Police Lt. Paul Vance said law enforcement has already used helicopters, dogs, and the State's Major Crimes Division to find Wiley.
Spot checks have been set up on Main, Valley, and Prospect Streets.
In addition to the spot checks, a Facebook page has been set up for people to leave tips with information relating to her disappearance.
"This is not a young lady who would walk away from such a life," Martin said. "This is not a young lady who would put her family through this much grief. This is, however, a young lady who is full of life, full of energy, and full of the hope that her future is bright."
Martin pleaded, with tears in her eyes, for help finding her daughter.
"I am asking, I am pleading with the public, as a mother who wants her child home, she has her family who wants her home, she has friend who want her home. We need your help, "Martin said.
She pleaded with anyone who has information to come forward.
Alyssiah is 5-feet 6, weighs 150 pounds and has black hair and brown eyes.
