A plea to the public today from the family and friends of a missing St. Catharines man.

No one has seen 43-year-old Darrell Riehl since last Tuesday after leaving his job at the Burke Group of St. Catharines around 5 p.m.

Darrell has a medical condition and did not have his medication with him. The worry is he may have suffered a stroke or heart attack, rendering him confused or unconcious.

His family says Darrell had no reason to walk away from his life and they fear for his safety.

Darrell is white, 5'11 and 290lbs. He has a dragon tattoo on the on the back of his shaved head, sports a reddish-gray goatee and his left earlobe is pierced.

He was last seen wearing a burgundy short sleeve and black pants.  He was driving a 1999 Ford Explorer, dark green, license plate number BKXC 583.  It also has a sticker on the drivers side rear window that reads "silly boys are for girls"

Darrell is known to frequent fast-food restaurants and always carries his iPhone with him. 

Anyone who has any information, or who may have seen him, is being asked to call police.
