PEARLAND, Texas -

There are new developments in the case of a teenage girl found dead in a Pearland home two months ago.

Police say a male suspect has been arrested and charged with capital murder in the death of Arrijana Hill.

Hill, 16, was found dead March 21 inside a home in the 3200 block of East Cedar Hollow Drive.

According to Pearland police, Hill was pregnant with twins at the time of her death and a paternity analysis determined the suspect was the father.

"They were looking at this suspect from the beginning. Had to get some lab results back to build a strong case," said Lt. Patrick Savage, with the Pearland Police Department.

The suspect, now 17 years old, was an acquaintance of the victim and attended Dawson High School with her. They say he was 16 at the time of the crime.

He was arrested around noon Tuesday at Pasadena Memorial High School and transported to the Brazoria County Juvenile Detention Center.

A Pasadena ISD spokesperson said the teen was transferred to the district on March 27, less than a week after Arrijana was killed. The Galveston County Medical Examiner's Office listed the preliminary cause of Hill's death as manual strangulation and stab wounds.

"Because more than one person was killed, charges were enhanced to capital murder," said Lt. Savage.

The suspect is being treated as a juvenile for now.

"Today was definitely helpful in the starting more of the healing process and a little more closure for us and my family," said Opal Hill, Arrijana's mother. “My daughter had a delightful spirit -- always smiling, always happy, so I continue to remember her as that person who was always happy and always in a good mood and smiling about something.”
