NORTH CHARLESTON, SC (WCSC) - A third Summerville resident has been arrested in connection with a Massachusetts double murder, and authorities say he is the man who pulled the trigger.

According to Brockton Police Chief Emmanuel Gomes and Plymouth County District Attorney Timothy Cruz, officers have arrested 25-year-old Guerry Hickman, of 5280 Copley Circle in Summerville.

Gomes and Cruz say Hickman shot and killed Tashawn Leslie and Tyrelle Baker in Brockton, Massachusetts on Dec. 29, 2012. Hickman is charged with two counts of murder, unlawful possession of a firearm, and unlawful possession of ammunition.

He is being held in North Charleston, according to authorities.  He will be taken back to Plymouth County to face the charges.

Hickman's arrest comes one day after North Charleston police arrested two others, 32-year-old Anthony Rivera and 27-year-old Crystal Jean Mergenthaler, at the same home on Copley Circle after Massachusetts State Police Department investigators told police they were suspects in their murder investigation.

A police report states that authorities think Rivera spoke to one of the victims before the killings.

The report also states that after his arrest Rivera said he wanted to speak to investigators in private and agreed to ride back to City Hall for questioning.

Police also said they found drugs in the home, and Mergenthaler was arrested on narcotics charges and booked at the Dorchester County Detention Center.  She has since been released on a $30,000 bond, according to Major John Garrison with the Dorchester County Sheriff's Office.

Massachusetts police say Rivera was also wanted for a burglary in their jurisdiction.

At this point, it is unclear if Rivera and Mergenthaler are still considered suspects in the murders.

A release from the Plymouth County DA's office said no further information would be released and no further comments would be provided.
