PORTLAND — A New Jersey man admitted Tuesday in federal court to charges stemming from the robberies of two U.S. postal carriers and burglaries of two U.S. post offices in central Maine.

Lance Funderburk, 31, of Orange, New Jersey, pleaded guilty in U.S. District Court to four felonies, including two counts of robbery of a U.S. postal carrier, each punishable by up to 25 years in prison and fines of up to $250,000 apiece.

He also pleaded guilty to two counts of conspiracy to rob U.S. postal carriers and to burglarize U.S. post offices, and one count of burglary of a U.S. post office.

Each of those crimes carries a maximum punishment of five years in prison and a fine of up to $250,000.

Prosecutors agreed that Funderburk should be allowed to appeal any sentence over 105 months.

He may be required to pay restitution of roughly $2,000 for damage to the two post offices, $1,074 for a laptop stolen from one of the post offices and $1,740 for stolen checks cashed by Funderburk and his co-defendant.

Investigators said Funderburk and an accomplice, Winston O. McLeod, 31, of Auburn, robbed two letter carriers in Lewiston and burglarized post offices in Paris and North Monmouth in January.

McLeod has pleaded guilty to the same charges as Funderburk, plus an additional count of burglary of a U.S. post office.

His sentencing has not been scheduled.

Funderburk was arrested Jan. 22 in Rumford in connection with the alleged burglaries and robberies.

On Jan. 20, postal inspectors were notified of the armed robberies of two postal carriers just minutes apart in Lewiston, according to an affidavit found in court papers.

Neither carrier was injured.

The first robbery happened at 20 Davis St.; the second at 480 Main St., according to the affidavit.

Both carriers were threatened with knives.

The robbers demanded keys from the carriers, according to the affidavit.

Later, during a vehicle search, police recovered several checks written to different recipients, evidence believed to be related to the burglaries and robberies.

Entry into the Paris Post Office was made through a window under which investigators found two cellphones in the snow, according to the affidavit.

One of the phone’s lock screens had an image of a man and a woman. Using facial recognition software, analysts were able to determine the man in the image was McLeod.

Later, during a search of a vehicle in which Funderburk was hiding, police found evidence linking him to the crimes, including work gloves; lighters; Vaseline; assorted keys, including those stolen in the robberies; a key fob; a black multitool; $1,005 in cash; a black matte butterfly knife; and four cellphones, according to the affidavit.

Funderburk was summoned to the Rumford Police Department, where he was arrested and later charged.

During a search of Funderburk, officers found two postal keys, according to the affidavit.
