A Rhode Island man charged with a 2007 homicide in Brockton has been indicted in the fatal double-shooting of a brother and sister in that city about 2 1/2 years later, authorities said Tuesday.
John V. Monteiro, 27, was indicted Monday on two counts of murder and other charges in the 2010 shooting deaths of Maria DePina and her brother, Jorge DePina, both in their 20s, the office of Plymouth District Attorney Timothy J. Cruz said in a statement.
Monteiro is being held without bail at the Plymouth County House of Correction on a murder charge in the July 2007 slaying of Gregory Goncalves Jr., 28.
He will be arraigned in Plymouth Superior Court in Brockton on the charges in the DePina case later this month, the statement said.
Monteiro, who has a prior firearm conviction, is alleged to have forced his way into the siblings' apartment on the morning of Jan. 21, 2010, shot the pair in the head, and later sold the firearm, according to prosecutors.
An 11-year-old boy was found unharmed inside the apartment after the slayings, authorities said.
A spokeswoman for Cruz said the office would not comment on a motive for the slayings before the arraignment, or the relationship of the child to the victims. Neighbors said at the time that the boy was Maria DePina's son.
The victims' relatives could not be reached for comment Tuesday. It was not clear who is legally representing Monteiro.
In the 2007 case, authorities allege that Rodney Gurley of West Bridgewater hired Monteiro to kill Goncalves because he thought Goncalves murdered his uncle in 2001, according to a press release issued by federal prosecutors in Boston last July announcing Gurley's conviction on an unrelated drug trafficking charge.
In a statement, Cruz decried the shootings of the DePina siblings.
"This was a brutal crime that shocked this community,'' he said.
