RADNOR, Pa. (CBS) – Police in Radnor (Delaware County) are again appealing to the public for help as they continue looking for a personal trainer who’s been missing for two weeks.

Police are hoping that someone may have seen Gerald Christopher, who hasn’t been seen since the early-morning hours of June 1st. That’s when he left the apartment he shares with his fiancée in the St. Davids section of Radnor.

[EDITOR'S NOTE:  Christopher's body was identified two days later.  See subsequent story.]

Police have conducted numerous interviews with family and friends and say it appears the 45-year-old man wasn’t himself in the days before he disappeared.

At this point, Sgt. Andrew Block says, they don’t suspect foul play.

“He left his personal belongings behind as well as his vehicle, so his wallet, cell phone, computer, and whatnot were left at the apartment,” Block told KYW Newsradio today.  “We believe he may be operating a black-and-yellow racing bike.”

Investigators say he often rides in the Valley Forge Park area.

Police are poring over his computer and cell phone to see if there’s any information that could lead them to Christopher.
