Police arrest one alleged Craigslist robber after tracking the e-mail address he used to negotiate meeting place with victim

Boston Police report the arrest of one of two teens they say convinced a suburban man advertising a laptop and phone to meet them in Dorchester and then robbed him at gunpoint on Oct. 26.

Omar Gray, 18, of Roxbury, will be arraigned Monday in Dorchester District Court on a charge of armed robbery following his arrest yesterday by detectives from two police districts and the BPD SWAT team.

Police say Gray negotiated the meeting place with his victim via e-mail, and that proved his undoing:

Thanks to some dogged and determined police work, detectives were able to secure the identity of one of the suspects by back tracking an email address used by the suspect during negotiations with the victim.

The other suspect remains at large.

Innocent, etc.
