Prince George’s County police said they have arrested three men who committed more than 50 residential burglaries in Oxon Hill and Fort Washington area this year.

The suspects were arrested after a weeks-long investigation that began after detectives noticed similarities in a large number of burglaries of single-family homes whose residents were away at the time of the break-ins. Police said they believe the suspects committed 54 burglaries in Prince George’s since December.

The thieves took mainly jewelry, firearms, televisions and cash, police said. In one case, burglars stole a safe containing more than $69,000 worth of jewelry and $14,000 in cash.

The suspects, charged with burglary, were identified as Anthony N. Edwards, 40; David B. Neal, 24; and Jamal Cooke, 21, all of Oxon Hill. Prince George’s police said they believe the suspects also are connected to burglaries in Fairfax County.

This week, aided by information provided by Prince George’s police, Fairfax police said they arrested two men and a woman and charged them in four burglaries in Fairfax. The suspects were identified as Craig Hopta, 29; Michael Lewis, 29; and Diana Seaborn, 34, all of Maryland. It was unclear the Fairfax suspects and the three men arrested in Prince George’s were part of the same alleged burglary ring.
