32-year-old man allegedly stabbed cousin's wife and three young children to death and then blamed it on MS-13

Just a few days after authorities took a DNA sample from Mathew Locke, they were able to match it with the one taken from the crime scene of the Bermudez murders

                            32-year-old man allegedly stabbed cousin's wife and three young children to death and then blamed it on MS-13

Thanks to DNA found on the body of one of the Bermudez children, investigators were able to link their murders to a relative. Mathew Locke, 32, was arraigned on September 5 on four counts of murder and ordered to be held without bail in the Western Worcester District Court.

Joseph D. Early, the Worcester District Attorney, said that Locke stabbed Sara Bermudez and her children — eight-year-old Madison, six-year-old James, and two-year-old Michael — at their home in West Brookfield. Their bodies were discovered on March 1. Court documents show that the police had got a DNA sample from Locke on March 19. Just a few days later, they were able to match the sample with the one taken from the crime scene in the bedroom where the mother and children were stabbed to death.

Authorities believe Sara and her children were murdered on February 28 when Moses Bermudez, her husband and the kids' dad, was in California for work. Locke is Bermudez's cousin and was held on a $10,000 bail since March 26 on charges that he lied to authorities. Investigators also said the man had lied about the relationship he had with Bermudez and had reportedly told them that he hadn't been to their home for at least two months before the murders happened.


Authorities stated in the court documents that Locke's car was spotted leaving his home and returning later in the evening on February 28. The documents added: "Witness statements reported that Mathew Locke was not at his residence prior to the homicides and had returned to the residence shortly after they occurred." 

The bodies of the mother and her children were discovered in the upstairs bedroom by Carlos Bermudez, Moses' father. Early stated that they had all been stabbed and there were signs of an attempt to set the room on fire. 

During a news conference outside the Western Worcester District Court, Bermudez could be seen standing behind Early as the district attorney made the announcement of the murder charges. Carlos and one of Moses' sisters were also there. Moses had said that if the investigators were able to find DNA in the bedroom then they would definitely be able to find the killer because his wife was a meticulous cleaner and only immediate family were allowed into that room.

Locke was seen arriving at the courthouse in a state police cruiser moments before the noon press conference took place. He is currently serving a sentence from the Palmer District Court in connection with a vehicle parts theft. He is scheduled to appear in court on the murder charges on October 18.
