UPPER DARBY, Pa. (WPVI) -- Police in Upper Darby are asking for the public's help in finding a mother of two who has been missing since last summer.
25-year-old Amanda De Guio was last seen leaving her Drexel Hill home in June 2014.
Upper Darby Police Superintendent Michael Chitwood along with Amanda's mother Joanne and sister Nicole pleaded for her return in a Thursday morning press conference.
"We have come to a conclusion that Amanda is probably the victim of some type of foul play," Chitwood said.
Upper Darby police fear the young mother is likely dead.
Her family says after complications with her first child, Amanda became addicted to painkillers then moved to heroin and in the months before her disappearance became involved in prostitution
"Our main goal is to get Amanda back, get some type of closure," Chitwood said.
Amanda, who also goes by the names of 'Gianna,' 'Adrianna' and 'Stacy,' is described as a white female, approximately 5'2 to 5'3, 115 to 125 pounds, with a thin build, brown hair, and blue eyes.
She has a number of tattoos including an Italian boot, the word 'Tommy' on her right torso, and the initials 'SC' on her left ring finger.
Police say she likes wearing wigs.
Chitwood says Amanda is a known prescription drug and heroin abuser and is known to be involved in prostitution.
"We know she is in a bad way, bad place, if she's out there she needs to know it's safe to come home," Joanne said.
Amanda is the mother of a 3-year-old and a 5-year-old.
"She has two small children that miss her dearly that we have no answers for. It is so important that we have some type of closure and answers for her children," Joanne said.
The family reported Amanda missing in August 2014.
Nicole, with a sister's prayer in her hands, said it wasn't unusual for Amanda to leave, but the family became concerned when she stopped contacting them on the phone.
"We said enough is enough. The no phone contact is very scary and that became very unusual. It wasn't unusual for her to necessarily leave, but it was unusual for no phone contacts. Enough was enough and we said we have to do something about this," Nicole said.
Investigators have reports she was last seen in Kensington.
Amanda's family is asking anyone with information to contact police.
"We're concerned for her safety and want her to come home. We want our Amanda back," Nicole said.
