US: Family of 6 found dead in Texas in apparent murder-suicide

According to the news, the Allen police received a request from a friend of one of the brothers, who had previously shown suicidal tendencies, to perform a welfare check on the family.

Local law enforcement officers arrived at the residence in the wee hours of Monday and found the six dead-bodies, which were identified later as the family members, including both parents, an elderly grandparent, two brothers and a sister.

The youngest siblings were 19 years old.

Reportedly, the two brothers had entered into a suicidal pact intending to end their own lives and kill their family to spare them from the grief; the suicide note posted on one of the boy's social media said.

The exact circumstances of the deaths are yet unknown, as the investigations are still ongoing. The police believe the murder-suicide may have taken place on Saturday night based on the evidence found in the house, the news stated.

The neighbors did not hear anything suspicious; no gunfire was reported at the time of the incident, though it was disclosed that the 21-year-old brother had legally purchased a gun prior to the incident, NBC-DFW cited the police mentioning it.

The family emigrated from Bangladesh and had no known relatives in the state.
