KENSINGTON (WPVI) -- A mother says she is desperate to find her daughter.
She's asking anyone with information to come forward, and has even increased the reward for help.
Susan Primavera hasn't heard from her daughter, Jill, in over four years.
"She stopped contacting, and I started putting my feelers out and what not, and nobody heard from her," said Susan Primavera.
The now 31-year-old was last seen on April 12, 2012, talking to a friend at the intersection of A and Allegheny in Philadelphia's Kensington section.
Her mother says Primavera has a history of being bipolar and involved in drugs. But she says none of that matters.
"I just want to tell her to come home. I mean our whole family just wants her to come home," said Susan Primavera.
Primavera has three daughters and her family says they miss her.
"They're getting old enough now, and they do know that we're the grandparents and that they do have a mom, and they do know their mom is missing," said Susan Primavera.
Primavera is described as a white female, 5 feet 5 inches tall and about 140 pounds.
At the time of her disappearance, she had blonde hair with red highlights.
She also has a couple of tattoos. One on her right arm is a picture of Jesus. And on the back of her neck is a flower that reads "Gina Grand Mom".
"If anybody has seen her just reach out and tell us, or if anybody has any information on her just please let us know," said Susan Primavera.
As an added incentive, the Citizens Crime Commission is administering a $10,000 reward for the information on the whereabouts of Primavera.
