A couple and their teen daughter were found dead in their 19,000 square foot home in a possible murder-suicide in one of the wealthiest suburbs of Massachusetts.

Rakesh Kamal, 57; his wife, Teena; and their daughter, Arianna, 18, were found Thursday evening at their home in Dover, Massachusetts, Norfolk County District Attorney Michael Morrissey said at a news conference on Friday.

The home, which is located approximately 20 miles southwest of Boston, is 19,000 square feet and is worth $6.8 million.

Authorities said that Arianna was a student at Middlebury College in Vermont and home for Christmas break.

Morrissey revealed that local authorities received a call on Thursday at approximately 7:30 p.m. after a concerned family member stopped by the home after they did not hear from the family for a couple of days. 

When the relative arrived at the mansion, they told police that they had found one of the victims.

During a search of the home, local police found all three victims within the home. Massachusetts State Police officers found a firearm near the husband, Morrissey said. 

"I'm led to believe that it's safe for me to tell you that this is probably a domestic incident," Morrissey said.

A sergeant with the Bronxville Police Department, which is located in a suburb of New York City, killed his wife and sons, 10 and 12, in a murder-suicide, authorities said Saturday. 

The bodies of Watson Morgan, 49, his wife Ornella, 43, and their sons were found with gunshot wounds in their nearby New City, New York, home late Friday after he didn’t show up for his shift, and the Clarkstown Police Department did a welfare check. 

A handgun was also recovered at the scene. 

"At this phase in the investigation it is believed that Watson killed his wife and two children, prior to killing himself with a self-inflicted gunshot wound," the Clarkstown Police Department said.

Morgan was a 16-year veteran of the department and had been promoted to sergeant in 2016. Before that, he served with the NYPD from 2000. 

"Our hearts go out to Sergeant Morgan’s extended family," Bronxville Police Chief Christopher Satriale said. "Our thoughts and prayers are also with his Bronxville Police Department family."

He added that the murders left the department with "profoundly broken hearts at the senseless loss of innocent lives."

The Clarkstown Central School District, where the two boys had attended school, sent a letter to parents Saturday over the "tragic loss," according to the New York Daily News.
