Two young Texan brothers entered into a murder-suicide pact and killed their entire family, police in Texas have said.
In a note posted on Instagram, 19-year-old Farhan Towhid said he and his 21-year-old brother Tanvir made an agreement to kill their sister, parents and grandmother.
"Hey everyone. I killed myself and my family," the note read.

Farhad gave a twisted justification for the mass killing.
"If I killed just myself, they would be miserable," he wrote.
"I love my family. I genuinely do. And that's exactly why I decided to kill them."
