Man sentenced in 2010 murder, attempted murder

Gregory Nierenberg, 24, pleaded guilty to charges in June 2013


JACKSONVILLE, Fla. – A 24-year-old man was sentenced this week to 40 years in prison for murder in the second degree and 25 years in prison for attempted murder, both which carry a 25-year minimum mandatory.

The Office of the State Attorney said Gregory Michael Nierenberg, 24, and his girlfriend were at Frederick Stalling's home in October 2010 when Nierenberg and Stallings, 51, got into a fight over drugs.

Nierenberg shot Stallings in the head and ran away from the home, firing shots at a second victim, officials said.

Nierenberg got into a vehicle and left the scene, according to officials.

Stallings, who was taken to a hospital, later died.

Nierenberg pleaded guilty to the charges in June 2013. His prison sentences will run concurrently.
