Man chased and gunned down in Brooklyn; Staten Island man shoots girlfriend's relatives in separate incident

A 68-year-old man who had just attended a wedding in Brooklyn was chased and fatally shot three times by a gunman still on the run, police said Tuesday.
Yingguan Chen, dying from gunshots to the head, chest and forearm, barged into a Popeyes Chicken on Seventh Ave. in Sunset Park Monday night after being blasted on nearby 61st St., police and witnesses said.
“Somebody help me! Call the police! Call the police!” he yelled, according to a manager at the fast food joint who heard details from a colleague.
“One of the customers ran over to the counter and grabbed a bunch of napkins. He was telling the guy, 'Sit down! Sit down!’” said the manager, who refused to give his name.
A police source said Chen also told the workers in Mandarin “he was going to die.”
Chen was pronounced dead at 10:03 p.m. at Lutheran Medical Center.
On Tuesday a bloody handprint remained on the eatery’s door.
Surveillance video from the fast food joint captured a cowardly criminal wearing a black trenchcoat and pink hat discarding the .22-caliber pistol he used in the heinous execution, police sources said.
The victim, who had no criminal record, had earlier attended a wedding at the nearby Golden Imperial Restaurant, police said.
Chen’s wife told police she knew of no reason why her husband would be gunned down.
In a separate incident on Staten Island, a man moving out of his girlfriend’s home shot and wounded her brother and nephew who tried to intervene in a dispute, police said.
Cops said Edward Garrins — who was still at large — flipped out after Sheila Holmes confronted him about what he planned to take with him as he moved out Monday night.
Holmes fell as the confrontation got physical, and her 15-year-old nephew and 37-year-old brother — who had been playing video games downstairs — rushed to help, according to sources.
That’s when Garrins pulled a .45-caliber gun from his waistband and opened fire, striking the 15-year-old in the right shoulder and hitting the dad, Anthony Jewell, in the left arm, according to sources.

Garrins has an open warrant for failure to appear in court for a disorderly conduct charge and has 11 prior arrests, including for assault, robbery and possession of a loaded gun, police said.
