Four days after her son never made it home to Montgomery County, Pennsylvania from his college in Rhode Island, Janet Royer made a public plea for his safe return.
"Matthew, if you can hear this, no matter what the circumstances are, you friends and your family, we all love you. We're here for you," she said and asked for him to contact her. "We will come anywhere, anyplace, anytime for you."
Janet Royer spoke during a brief news conference held by Pennsylvania State Police who say they are investigating Matthew's disappearance as a missing person's case, although "at this point, it may be a voluntary move on Matthew's part," said a spokeswoman for state police.

Matthew is from Collegeville, Montgomery County. He texted his mother on Thursday night saying he was headed home. He turned in the keys to his college apartment and got on the road around 6:30 p.m., according to investigators.
Matthew’s mother says it out of character for her son to disappear without telling anyone, especially since he was scheduled to work at Skippack Golf Club this past weekend.
“He's not a child. He wouldn't tell me he's doing something and then not come home, he's responsible 21-year-old,” said Royer.
While police, family and friends do not know where Matthew is right now, they do have some clues about where he has been or where his car has been up through 1 p.m. on Friday.
So far, this is the timeline investigators have been able to sketch together:
Thursday 6:30 p.m. -- Matthew Royer leaves his Rhode Island apt. and heads for home
Friday 1:58 a.m. -- police trace Royer's last cell phone ping -- or signal to a cell tower -- in the Allentown area.
Friday 2:07 a.m. -- Surveillance video of Matthew buying gas and water at a Sunoco along Route 100 in Allentown
Friday 1 p.m. -- Royer's car seen at Route 501 and U.S. Route 422 in Myerstown, Lebanon County, Pa.
That last location is about an hour and 15 minutes from Royer's home.
"His car would be stuffed with dirty laundry, full of stuff...he was coming home," said Janet Royer.
Family members and neighbors passed out flyers Sunday in an effort to find the missing college student.
“It's a nightmare it's a bad movie,” said Royer. “I can't believe it’s happening to me. He was coming home from college to start the summer.”
Royer is traveling in a silver 2008 Chevrolet Cobalt with a Pa. license plate that reads “GZR9059.”
Royer is described as a white male standing 6-foot-1 with blue eyes and brown hair. If you have any information on his whereabouts, please call the Pennsylvania State Police-Skippack at 610-584-1250.
"We are her for you," his mother said in her plea. "We love you and miss you."
