MARTINEZ -- A man killed in Antioch last month died protecting his younger brother and a 2-year-old girl from a shooter enraged over his missing gold grill dental jewelry, according to prosecutors.

Armoun Page, 19, of San Francisco, pleaded not guilty to murder, attempted murder and other felony charges on Thursday in the Sept. 28 shooting that killed 24-year-old Brentwood resident Khalid Bragg and wounded Bragg's 20-year-old brother, Taaron Bragg, of Suisun City.

Page and the brothers were visitors in the same residence in the 2200 block of Banyan Way in Antioch when he kicked down the door of a bedroom containing the brothers and a 2-year-old girl and started firing because he was angry over his missing gold grill, deputy district attorney Jill Henderson said.

Khalid Bragg tossed a 2-year-old girl who had been in his arms across a bed to get out of the way of the gunfire, and threw himself on top of Taaron Bragg to shield his brother's head and upper body, Henderson said.

Page allegedly fired five shots. Khalid Bragg was killed, and Taaron Bragg was hospitalized with gunshot wounds for which he remains hospitalized in critical condition, Henderson said.

The toddler was not wounded. Her relationship to the Bragg brothers was not known by prosecutors Thursday.

Page remains in County Jail in lieu of $4.15 million bail. His preliminary hearing is scheduled for Oct. 21.

Page's public defender could not be reached for comment Thursday.
