PHILADELPHIA (CBS) - An alleged killer has been ordered to stand trial after confessing to “the unthinkable,” according to Philadelphia police.

Donald Newsome, 32, is accused of repeatedly stabbing his former girlfriend last month, then setting fire to their Mt. Airy home, because she wanted to break up with him (see previous story).

Homicide detective James Pitts has testified that Newsome admitted he stabbed 27-year-old Rosa-Lyn Daniels because she want out of their two-year relationship, so he got upset and took matters into his own hands.

“I just want justice for my daughter,” said the victim’s mother, Rafeeqah Sanders, after suffering with other family members through listening to the details of the murder in court.  “She didn’t deserve to die like that. She had two beautiful children and she had a lot of life left.”

Sanders says Newsome (right) is not the father of the children, aged two and six, and “it’s just not fair.”

Defense attorney Michael Medway says he just got the case, but his client has indicated that what is in his confession may not be exactly what took place.

Newsome, ordered held for trial, is being held without bail.
