He threatened the life of an 8 year old girl and killed a drug dealer. Here’s how long he will spend in prison.

A New York serial burglar threatened to kill an 8-year-old and killed a drug dealer. Now, he will remain behind bars for the rest of his life.

Last week, U.S. District Judge Joan M. Azrack ordered Tyrone L. Robinson spend the rest of his life in prison for the shooting death of Johnathan Isaac. Robinson was found guilty and convicted by a jury for murder, seven counts of robbery, attempted robbery of drugs and drug proceeds, seven counts of unlawful use, four counts of being a felon in possession of firearms and ammunition and brandishing and discharge of firearms.

For a year, Robinson and his crew committed violent crime sprees and a reign of terror by invading drug dealer homes in Nassau and Suffolk counties in New York, according to federal prosecutors.

On March 25, 2016, the armed defendant invaded a Lake Grove,, New York, home and threatened to kill an 8-year-old girl if she did not find the money in the residence. The next day, neighbors called the police after sighting Robinson again at the Lake Grove home. However, the defendant fled the scene leaving behind his cell phone.

As a result, investigators logged into Robinson’s online account, where his Google search showed directions to his victims' residences. In addition, the defendant had a habit of searching online for related news to the crimes he committed.

However, on May 3, 2016, Robinson’s home invasion turned deadly after he shot Isaac and another victim in the Freeport, New York, neighborhood.

“Robinson’s violent crime spree extended not only to possessing illegal drugs and weapons, and committing home invasions, robberies and murder, but also to threatening to take the life of an innocent 8-year-old child. Today’s lengthy sentence serves to protect our communities, including our children, while sending a strong message to violent offenders like the defendant that they will be held accountable to the fullest extent of the law,” U.S. Attorney for the Eastern District of New York Breon Peace said.

The 35-year-old Robinson was merciless and often zip-tied and pistol-whipped his victims. The successful conviction and investigation were due to the Project Safe Neighborhood program. The program's objective included the efficient partnership of federal, state and local authorities in combating violent crimes in the state.

“Today’s sentence ensures that a serial predator will never be set free to inflict violence within our communities. We commend the work of the ATF’s Long Island Firearms Task Force and our partners from the Nassau and Suffolk County Police Departments and United States Attorney’s Office for their steadfast commitment to investigating these crimes,” said John B. DeVito, Special Agent-in-Charge, Bureau of Alcohol, Tobacco, Firearms and Explosives, New York Field Division.

Azrack ordered Robinson to serve additional 84 years consecutively to the life sentence for the other charges.
