A man held in a hostage drama earlier this month has been charged with murder in a fatal shooting in West Philadelphia in April.

Demetrius Young, 20, was arrested in prison and charged with shooting and killing Marcus Smith, 28, of the 5700 block of Filbert Street, at 60th and Market Streets at 3:45 a.m. on April 1, police said.

Investigators have not disclosed a motive in the shooting or what led them to arrest Young.

Young, of the 4200 block of Ogden Street, and two other men were arrested early May 2 after they held the owners of a Chinese restaurant and their young daughter hostage when a robbery went awry, police said.

The trio gave up after a hostage negotiator convinced them to surrender.

The robbery at the Hong Heng Restaurant, 4201 Ogden St., was thwarted when a passerby who saw the three men enter the building became suspicious and called police.

A preliminary hearing on the murder charge is set for May 30.
