Cops collared the 19 year-old brute that shot a girl walking home from school with her little sister last week, cops said.

Rashawn Williams shot Tamia Tucker,14, outside of a gas station on the corner of Sutter and Euclid Avenues around 3:30 p.m. Nov. 22, cops said.

“I don’t want to die!” she wailed as gas station clerk Issic Alsaidi, 29, ran to her side.

He was picked up by cops at his Fountain Ave. home this morning around 7 a.m., cops said.

Williams has been charged with assault, criminal possession of a firearm and reckless endangerment, cop said.
