Suicide Pact Posted On Instagram Leaves 6 Dead: 'I Killed Myself And My Family'

Six members of a Texas family are dead after two brothers allegedly carried out an apparent mass murder-suicide pact, local police have said.

Officers of the Allen Police Department found the family dead with gunshot wounds in their Pine Bluff Drive home on Monday just before 1 a.m. when they attempted to perform a welfare check, KTVT reported.

Police identified the bodies as 21-year-old Tanvir Towhid, 19-year-old twins Farbin Towhid and her brother Farhan Towhid, their 54-year-old father Towhidul Islam, 56-year-old mother Iren Islam and 77-year-old grandmother Altafun Nessa.

Police believe the shooting took place on Saturday night based on evidence found, KXAS-TV reported.

The two brothers are suspected to have carried out a murder-suicide pact to kill their family members before taking their own lives. Police found a suicide note left by Farhan Towhid on his now-inaccessible Instagram.

"Hey everyone. I killed myself and my family," he wrote on the post that linked to a lengthier, now-removed note on Google Docs revealing the two brothers' battle with depression and the details of their plan. Google stated the document was taken down because it was in violation of their terms of service.

Farhan Towhid said his older brother, Tanvir, proposed to kill themselves along with the rest of their family if they were unable to fix their problems in a year.

"The plan was simple. We get two guns. I take one and shoot my sister and grandma, while my brother kills our parents with the other. Then we take ourselves out," Farhan Towhid said in the document.

He explained, "If I killed just myself, they would be miserable. I love my family. I genuinely do. And that's exactly why I decided to kill them."

Police confirmed that the older brother was able to legally purchase a firearm recently.

Sgt. Jon Felty of the Allen Police Department said he had never seen an incident like this in his 21 years of service.

"I've been here 21 years in Allen. We have never had an incident like this in the 21 years that I've been here," Felty was quoted as saying. "So, as you can imagine, it's just a tragedy. There's no other way to describe it."

Felty said the investigation is still ongoing.

The department is urging people with any information on the incident to report it to Investigator Tim Dowd at tdowd@cityofallen.org or by phone at 214.509.4252.
