Cesar Mazza, 25, has been held by the Pittsburgh police on two counts of criminal homicide and a charge of kidnapping his 11-week-old son. Mazza, upset that his ex-girlfriend, 19-year-old Tionna Banks wouldn’t name their newborn son after him, fatally stabbed her and beat her 72-year-old grandmother to death.
The bodies of Banks and her grandma, Valorie Crumpton were found at the Crumpton home on May 7. Bank had failed to return to a group home for at-risk girls after she was given a weekend pass to visit Crumpton.
Mazza had a history of alleged violence against Banks and at the time the women were killed, Banks had a protection-from-abuse order against Mazza that required him to stay away from her. He was also awaiting trial on charges that he punched Banks, stomped on her abdomen and dragged her down some steps in November. When he failed to appear for his May 6 trial on the assault charges, police got a warrant May 8 for Mazza.
Unnamed witnesses told police they saw blood on Mazza and the baby May 4, when Banks was due to return to the group home. Mazza had a small cut on his palm, but it was "un-bandaged and did not seem in proportion with the large amount of blood on Mazza and the baby," one of those witnesses told police.
Mazza explained away the blood by claiming Banks tried to stab him because he forgot to bring her a pack of cigarettes when he was visiting and picked up their baby, the complaint said.
The other witness had seen Mazza leave Crumpton's house about four hours earlier with a cut on his hand and red liquid on his clothes. That witness assumed the red liquid was paint because that's how Mazza made a living, police said. In reality, police say, they later found Mazza had stabbed Banks 15 times and killed her grandmother Valorie Crumpton.
