A story from Allen, TX, a northern suburb of Dallas, very much buries the lead:

The bodies of six people were found inside an Allen home early Monday morning in an apparent mass murder-suicide, Allen police say.

Officers were asked to perform a welfare check at about 1 a.m. at a home on the 1500 block of Pine Bluff Drive. When officers entered the residence, they discovered the bodies of six people.

The names and ages of the victims have not been confirmed, but police said they included a grandparent, two parents and three children.

"It looks like two teenage sons entered into an agreement that they were going to commit suicide and that they were going to take their family members with them," Allen Police Sgt. Jon Felty told KRLD-AM Monday morning.

It has not been confirmed when the deaths took place.

Felty said there is no threat to the neighborhood and that there were no problems reported at the home, KRLD reported.

This is the actual last line of the story:

The family, Felty said, apparently emigrated from Bangladesh.

Allen Family of Six Killed in Apparent Mass Murder-Suicide: Police

Investigation ongoing into deaths of six family members inside Allen home

Another story, from CBS-DFW, says "Police said there’s a social media post by one of the victims saying he made a pact with his brother to kill his family and commit suicide." This story has no ethnic details and a bunch of links to generic suicide prevention links.

Instead of talking about suicide, let's talk about Immigrant Mass Murder, specifically the kind we call "Familicide" where an immigrant goes crazy and wipes out his or her entire family. Brenda Walker first wrote this up in 2007, with Diversity Is Strength! It's Also…Familicide.
