HOUSTON -- One suspect was arrested and another is wanted in connection with the shooting deaths of four young people in a Clear Lake home three years ago, KPRC Local 2 reported Friday.

More than 20 shots were fired inside the home in the 3700 block of Millbridge on July 18, 2003. Marcus Precella, 19; Tiffany Rowell, 18; Rachel Koloroutis, 18; and Adelbert Sanchez, 21, died at the scene.

A $100,000 reward was offered and police said a Crime Stoppers tip helped crack the case.

Christine Paolilla, 20, was arrested at her San Antonio home last night, officials said. According to investigators, she told her husband that her ex-boyfriend committed the murders.

She is now jailed on a capital murder charge.

Christopher Lee Snider, 21, of Crosby, is believed to be in South Carolina, officials said.

He was also charged with capital murder.

Sources told KPRC that Paolilla said Snider was looking for something to steal and "whenever he couldn't find anything, he just started shooting."

Paolilla is due in court on Monday.
