‘Hero’ killed in slay-suicide

A Manhattan man, distraught about a breakup, killed his ex-girlfriend’s cousin and himself yesterday in an apartment building near the Chelsea Market.

The cousin, 20-year-old Brandon Romero, “went down like a hero’’ while trying to wrest away a gun shooter Kenneth Waldron, 29, had pointed at the ex-girlfriend, said Romero’s brother, Frank, 24.

Brandon Romero had accompanied the woman to retrieve her belongings from Waldron’s apartment in the Fulton Houses complex, police said.

Romero was shot in the head and chest and stabbed.
