PHILADELPHIA (CBS) –– According to police we are now entering the third night in a row since a mentally-ill Philadelphia man has been seen.

He suffers from severe schizophrenia and as you can imagine his mom is worried sick.

45-year-old Frank Masciocchi is nowhere to be found, he’s a paranoid schizophrenic who requires strong medication.

His mom is heartbroken.

“I just don’t, I feel like he has vanished. I just want to find him. I just want to know where he is. What happened to him?” Mary Masciocchi said.

Frank was last scene Wednesday at around 5 p.m. just across the street from the group home he lives in at 24th and Penrose Avenue in South Philadelphia.

The Philadelphia Police Department lists Frank as an endangered person on its website.

Masciocchi’s sister tells Eyewitness News that without his medication his illness can debilitate him, he becomes disoriented and losses his ability to speak.

“This is like a nightmare” she said.

Because of his appearance, his family is pleading with anyone who sees him to not be afraid and to remember he is sick.

“He’s very afraid of being out at night. So for him to be away since Wednesday something has to be wrong,” she said.

At the Penrose Diner near where frank lives they have posted his picture hoping someone sees him on the street.

“Right now I’m trying to hold on,” Mary Masciocchi said.

Frank’s family has been all around the area looking for him. If you see him they are asking you to call police right away.
