ARLINGTON, Mass. (MyFoxBoston.com/AP) -- Autopsies have been scheduled for a husband, wife, and infant twin sons found dead in an Arlington apartment Monday.
Officers were called to the apartment at 45 Newland Road by another tenant in the building requesting a welfare check, Middlesex County District Attorney Marian Ryan said. When they arrived, they found the bodies of the family.
The victims were identified as Scott Jones, 43; Mei Kum Jones, 43; and Colt and Cameron Jones. Ryan said the twins would have turned one-year-old on Nov. 26.
"This is obviously a very troubling, very tragic situation," said Ryan.
Investigators have not yet said how the four died. Their bodies were removed from the home by the state medical examiner's office Monday evening.
A source told FOX 25's Ted Daniel that the scene was gruesome and the weapon involved was some sort of cutting tool.
Neighbors said the couple may have been having some marital problems.
"I know at one time my sister told me the police came because he threatened suicide," said the woman.
Arlington Police Chief Frederick Ryan said police were not looking for any suspects and there was no reason for the public to be alarmed.
"We're quite certain that the community is safe and people can go out and go about their business this evening," he said.
Stephen Trebino, who grew up across the street, said he often saw the couple walking with the babies. He said the man was nice to his father and would shovel the walk without asking when it snowed.
"He was friendly," Trebino said. "He was always working on the house, always go, go, go."
Mei Kum Jones had worked for Road Scholar, an educational travel program formerly known as Elderhostel. The company released the following statement:
"We at Road Scholar grieve the loss of our colleague, Mei Jones. Mei was a valued member of our team and her loss is deeply felt by all of us. As we grieve together, we can only imagine the impossible loss Mei's family must bear, and our deepest sympathies are with them. I'm sure you will understand, this is a terrible time for our community and we ask for your understanding as we grieve the loss of our colleague privately."
