NBC NATIONAL NEWS — A 19-year-old Texas man is facing murder charges after allegedly beating his younger sister to death.
Deputies said Estephani Boijseauneau, 17, was killed at her Magnolia home about 12:30 p.m. Tuesday.
Investigators said she suffered blunt force trauma to the head.
A witness said that the girl's 19-year-old brother, Jordan Abel Boijseauneau, beat her during an argument.
The witness, Jordan Abel Boijseauneau's 15-year-old girlfriend, was tied up with duct tape by her boyfriend during the assault, deputies said.
Once she managed to cut herself free, she called 911 from a neighboring home.
Jordan Abel Boijseauneau was found hiding inside a closet.
Officials said he tried to commit suicide by taking pills and stabbing himself in the chest with a knife.
He was taken to a hospital in critical condition, and was upgraded to stable condition on Wednesday.
Investigators said he will be booked and charged with his sister's murder as soon as he is released from the hospital.
Friends of the victim and the suspect said they never knew them to argue or fight.
"I always seen them together," said Norma Veneros. "Nothing bad, they didn't do anything. I was really great friends with both of them, they were really great friends."
Veneros said Estephani Boijseauneau would have been a senior in high school and had aspirations to get a cosmetology license when she graduated.
"The last time I saw her, she cut my hair," Veneros said.
The high school senior also loved babies and thought about becoming an ultra-sound technician.
"She was a real good person," said Veneros. "Quiet, really friendly, she was great."
