Kevin Darden was taken into custody for questioning on Tuesday in a fatal NYC subway push that killed an innocent 61-year-old man.

34-year-old Darden is reportedly a fugitive ex-con who has a 15-year rap sheet with 30 arrests, including one for trying to torch his brother’s house, according to the NY Daily News.

Darden was reportedly the target of a massive police search as a “person of interest” after the victim of the NYC subway push, Wai Keun Kwok, was killed beneath an oncoming train in the 167th St. station in the Bronx as his horrified wife had to watch. The man responsible for the horrific NYC subway push never said a word to Kwok before he shoved him to his death.

This isn’t the first time that Darden has been suspected of pushing someone in front of a NYC subway. The New York Post reported that Darden is suspected of pushing another Asian man toward a train at the West 4 St. station in Manhattan’s Greenwich Village on November 6.

Cops reportedly stated that the 51-year-old Asian man was thrown to the ground by an attacker who threatened, “Stay out of my way, I’m warning you.” The victim reportedly injured his hand and back, and was released after treatment at the New York University Medical Center, cops stated.

The man’s mother, Berlyn Joyce Jones, reportedly stated that her son has a mental illness and that he had not lived with her for many years. She reportedly reached out to him many times, but each time he told her he was “pulling himself together," according to the Digital Journal.

“I feel so, so sorry for those people and what happened,” stated Jones.

She added, “I know that won’t bring him back but I am so, so sorry.”
