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

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.
