A Hempstead man who stabbed another man repeatedly, inflicting a fatal puncture wound to his heart, is going to prison for 25 years to life in connection with the 2013 attack, authorities said.

A Nassau judge on Wednesday handed down the sentence to Luis Moreno, 38, following his June conviction on a second-degree murder charge and a weapon charge in the death of Darwin Hernandez, 28, of Hempstead.

Prosecutors said Moreno unleashed a vicious attack on the afternoon of March 2, 2013, behind a Clinton Street laundry business as Hernandez tried to defend himself and flee.

Hernandez suffered stab wounds to his chest, hand, abdomen, groin and head, according to the Nassau County district attorney's office. Authorities said they never found the murder weapon.

Defense attorney Jeffrey Groder said Moreno plans to appeal the jury's verdict.

"Since the beginning of the case, he's always been consistent in his position that he was defending himself and he maintained that position at the sentencing," Groder said Wednesday.

The Mineola lawyer said evidence showed his client told police he gave Hernandez money to buy food or drinks, and that a confrontation between the friends kicked off when Hernandez returned with nothing.

Moreno also told police the stabbing happened after Hernandez became aggressive and reached toward his waistband, Groder said.

Hernandez was unarmed, according to prosecutors.
