— A Raleigh man, who bought alcohol for his teen sister who was found dead a day after she was involved in a car crash, died Saturday from injuries he suffered while attempting to take his own life.

Last month, authorities determined Nicholas Scott Jenkins, 23, bought alcohol for Lauren Maria Jenkins, 17, and two friends before the March 17 crash.

Wake County District Attorney Lorrin Freeman said Friday that the county would not pursue charges against Nicholas Jenkins.

"These are difficult cases," Freeman said. "This is not inconsistent with how we handle other cases where a close relative has died and potential charges do not rise above a level of a misdemeanor."

Trooper D. Gray said Lauren Jenkins failed to yield as she attempted to make a left turn from Leesville Road onto Oneal Road and pulled in front of a car driven by Carly Brown. Gray said Brown told him Jenkins appeared to be injured as she and another girl in her car walked and then ran off after the crash.

Although investigators have not determined whether Jenkins' drinking contributed to the crash, Gray told a state Alcohol Law Enforcement investigator that he found a bottle of cognac in the car at the scene.

An application for a warrant to search Lauren Jenkins' iPhone says Gray obtained video of her "and several other youthful looking individuals in a hotel room consuming from what appeared to Hennessy Cognac and Cruzan Rum."
