A 20-year-old North Carolina man has been charged with murder in the death of a young woman found dead in her locked bedroom — and her brother says the man was one of her roommates.

Raleigh police have not said how Eric Gael Hernandez-Mendez knew Christina Matos, 20, or given a cause of death.

Matos’s brother, Abraham Matos, told the Raleigh News & Observer that Hernandez-Mendez was one of his sister’s two roommates at her Raleigh apartment.

Matos was found dead Sunday night after police received a 911 call reporting her as a missing person.

“I have a concern about a missing person,” the caller said. “I was really curious if her family called in about it. I have her address, I know where she was last seen. It was on Friday.”

Matos’s family, meanwhile, was reportedly at her apartment overnight Saturday after not hearing from her all that day, as CrimeOnline previously reported. According to ABC11, Yolanda Matos, her mother, had a key to the apartment but couldn’t open her locked bedroom door.

Raleigh police have been tight-lipped about the murder, revealing details in brief notations posted periodically on their public notice board.

Matos’s parents said their daughter was a student at Wake Technical Community College, taking radiology course, but the school told the News & Observer that while she had been enrolled in the fall, she was not enrolled in the spring semester.

“She was working two jobs,” her brother said. ”She made sure to pay all her bills and she liked to gift herself for the hard work she’d done.”

Hernandez-Mendez was booked into the Wake County Detention Center, but no information about him was immediately available.

Anyone with possible information on the case is urged to contact the Raleigh Police Department at (919) 834-4357 or visit raleighcrimestoppers.org.
