According to investigators, due to the opposition to their teenage daughter’s romance, the family of a 16-year-old girl was attacked, leaving her mother and brothers dead and her father in critical condition.

On Sunday four suspects, including the girl, were detained on capital murder charges just a day after the attack occurred on the rural East Texas home of Terry and Penny Caffey.

The Rains County Sheriff's Department said that Terry Caffey crawled almost 300 yards, after he was shot in the head, to seek help to a neighbor’s house. During this time his house was engulfed by flames with his wife and two sons inside.

The statement said that Penny Caffey, 37; Tyler Caffey, 8; and Mathew Caffey 13, were shot and stabbed multiple times.

The attack occurred on remote woodland of 20 acres where there were only two homes left between the small East Texas towns of Emory and Alba, located 60 miles northeast of Dallas.

The girl was found by the investigators at the home of one of the suspects. It remained unclear which of the suspects she was dating.

The statement said: "Early on in the investigation, it was revealed that the juvenile and one of the suspects were dating and made to break up," the Associated Press reports.

According to the sheriff's department, Charlie James Wilkinson, 19; Charles Allen Wade, 20; and Bobbi Gale Johnson, 18, all of Emory, were charged with three counts each of capital murder. They remained in Rains County Jail and the bonds were set at $1.5 million each.

The daughter, whose name was undisclosed, remained in Hunt County's juvenile detention center in Greenville.

On Sunday Terry Caffey was in East Texas Medical Center in Tyler in critical condition.
