DA: Records from their getaway Uber ride helped lead police to pair charged with a murder in Roxbury

Two men were ordered held without bail today at their arraignment on charges they murdered Alexander Mervin on Whittier Street on Jan. 11.

According to the Suffolk County District Attorney's office, Jerion Moore, 19, of Stoughton and Nicholas Sicellon, 18, of Dorchester, both had guns when they walked up to Mervin in a Whittier Street parking lot and opened fire, shooting him repeatedly.

Video captured by an MBTA public safety camera captured two men later identified as Moore and Sicellon as they left the scene and entered the Shawmut Avenue home of a relative of Moore. Sicellon then summoned an Uber that took them from the area minutes later.

The two men were identified through records linking Moore to the address the men entered and through the credit card and telephone number on record with Uber.

Neither man stayed low after the murder, authorities say. On Jan. 27, police arrested Moore at Ames Street and Ames Way in the Franklin Field development on gun charges. On Jan. 29, police arrested Sicellon on gun charges at Welles Avenue and Joseph Street in Dorchester.

Sicellon has remained held on $15,000 bail since his arrest; Moore was released and ordered to wear a GPS monitor after a judge reduced the $5,000 bail imposed at arraignment to $2,500 in February. He was taken into custody at his home in Stoughton on Saturday evening.

Innocent, etc.
