Murder suspect nabbed in West Phila.

Andrew Poole will be spending Christmas in the slammer after all.

The notorious West Philly triggerman - who had been on the run since cops said he shot two people, including a toddler, in September and then killed a man last month - was captured yesterday hiding out in a flophouse with four other accused criminals, law enforcement sources said.

Members of the police warrant unit and the FBI Fugitive Task Force tracked Poole, 22, to a house on Market Street near 50th at about 1 p.m., the sources said.

Police said the detectives first saw one of Poole's criminal cronies hanging out in front of the house. When they pounced, the unidentified suspect ran back into the house.

Sources said the investigators found Poole and the four other men hiding inside, with three handguns and an unknown amount of drugs.

One of the suspects might have been invovled in the September shootings, sources said. All four were expected to be identified today.

Poole was charged with murder and multiple counts of attempted murder, aggravated assault and weapons charges.

"This really is a blessing," said Kazmir Brandon, whose fiance, Tremayne Walker, was fatally shot by Poole in West Philly on Nov. 11, according to cops.

"This doesn't bring Tremayne back, but I'm grateful that [Poole] can't hurt another family," Brandon said.

Homicide detectives said Poole shot Walker twice in the back because he mistakenly believed Walker had snitched on him.

Friends of Walker, a promising Christian musician, staged a concert on Saturday to raise money for a reward. Last night, they were overjoyed.

"We're truly grateful. We can sleep, we can relax. Justice is going to be served, and he's going to be dealt with by the law, which is the right way," said Emmanuel Fuller, 22, Walker's brother and bandmate.

On Sept. 22, cops say Poole opened fire at the E.R. Tustin Playground, near 60th Street and Columbia Avenue, Overbrook, after a dispute. He seriously wounded 18-month-old Mehkee Gatewood and Carl Wallace, 31, police said.

Ironically, Poole was sentenced to three years' probation on Sept. 12 for illegally carrying a gun earlier this year. The district attorney's office said the sentence was fair, given Poole's lack of a previous record. *
