Cousins attacked, one killed by livery driver in Brooklyn

A pair of cousins were attacked and one was killed following an incident in the Gravesend section of Brooklyn, the NYPD said.

Police received a call just after 4:30 a.m. for two men assaulted at 1968 W. 9th St., between Avenue S and Avenue T.

Home surveillance video shows the two men on the ground, unconscious.

According to the NYPD, the victims, a 66-year-old man identified as Carlos Guaman, as well as a 52-year-old man, were rushed to Maimonides Medical Center, where the 66-year-old was pronounced dead, police said. The 52-year-old remains in critical but stable condition.

Authorities say the incident began as an argument between the driver of a livery vehicle and his two passengers. 

The driver allegedly got out of the car and repeatedly punched the men in their heads before fleeing the scene, heading northbound on W. 9 St.

"I think its shocking, I mean its appalling. I don't have any explanation of why some senseless violence like that would happen," a neighbor said. 

There are no arrests at the time. The identity of the victim is pending proper family notification.

The FDNY had conflicting reports Thursday morning of five people hospitalized after being found unconscious at the location.
