A 52-year-old man suspected of killing a 14-year-old and wounding his 15-year-old brother last week in Central City was arrested Thursday.

New Orleans police booked Gregory Johnson on a count of first-degree murder, two counts of attempted first-degree murder and aggravated battery in connection with the May 5 shooting that killed Miquial Jackson when a bullet pierced his head.

Johnson was found hiding just before noon Thursday in the 1500 block of LaSalle Street, about a dozen blocks from Josephine and Brainard streets, where the shooting happened.

Police earlier had arrested Randy Pittman, 49, Johnson’s roommate and alleged getaway driver, and booked him as an accessory and a principal to first-degree murder.

Police have said Johnson opened fire on the teens as he chased them through the neighborhood.

Witnesses told police that Johnson was “fussing” at the youths as they walked in the area. Police did not say why he might have been upset with them, but relatives said during a candelight service for Miquial that he, his brother and another teen might have bumped into Johnson as he bicycled past them.

A short time after the apparent argument, a Mercedes-Benz, driving the wrong way down a one-way street in the neighborhood, pulled up to the corner and stopped, police have said. Witnesses said they saw Johnson walk to the car, get something out of the back seat and then chase the teens before he opened fire on them.

While it is not clear whether Pittman knew what Johnson allegedly intended to do when Johnson called and asked him to meet him at the corner, police said there is no question he was aware of the subsequent shooting, then knowingly helped an alleged killer evade arrest.

Police found Pittman after the shooting at the home in the 2200 block of Baronne Street that he shared with Johnson. By that time, however, Johnson was gone.

Police said Pittman drove Johnson to the home and watched as Johnson gathered up some belongings before escaping.

Pittman remained jailed Thursday on a $1.5 million bail.

Bail had not been set for Johnson as of Thursday evening.
