The Bucks County District Attorney's Office reported four young men missing in the county Sunday night, ranging in age from late teens to early 20s.

County investigators identified the four as Mark Sturgis, 22, of Pennsburg; Tom Meo, 21, of Plumstead; Dean Finocchiaro, 18, of Middletown; and Jimi Tar Patrick, late teens, of Newtown Township.

Finocchiaro and  Patrick went missing last week, according to Bucks County police, while Meo and Sturgis were added as also missing late Sunday.

A Facebook post seeking leads said Meo is diabetic and was last seen around Routes 202 and 263 near Doylestown on Friday.

State police, along with detectives from Solebury, Middletown, Newtown, and Buckingham Townships, as well as Philadelphia, along with police dogs, executed a search warrant at a home in Solebury Township around 7 p.m. Sunday as state police helicopter circled the property, near Meetinghouse and Aquetong Roads.

Fox29 reported Monday morning that the search turned up a car belonging to one of the young men.

Investigators said they were unsure how the four men are linked other than as friends.

It was unclear whether that home had any connection to any of the missing youths.

Anyone with information is being asked to call the Bucks County radio dispatch at 215-598-7121.
