A parking dispute at a West Bank home devolved into tragedy on Father's Day when a man shot and killed his stepson and critically wounded his step-grandson, Jefferson Parish authorities said.

Mark Jones, 58, was arrested and booked with second-degree murder and attempted second-degree murder, said Capt. Jason Rivarde, a spokesman for the Jefferson Parish Sheriff's Office.

Jones' stepson, Tyrell Washington Sr., 40, of Marrero, was taken to University Medical Center with multiple gunshot wounds. He later died of his injuries, according to Mark Bone, chief death investigator for the Jefferson Parish Corner's Office.

Washington's 21-year-old son was in critical condition Monday afternoon with a gunshot wound to his neck, Rivarde said.

The shooting occurred about 10:45 p.m. on Father's Day at Jones' home in the 900 block of North Clark Lane near Westwego.

Jones and Washington were arguing over parking at the residence, Rivarde said. The argument got physical as the two began fighting. That's when Jones allegedly grabbed a gun and shot both Washington and his step-grandson.

Jones was taken into custody at the residence. He was being held Monday at the Jefferson Parish Correctional Center in Gretna in lieu of a $750,000 bond, court records said.

Just over 12 hours later, the Sheriff's Office responded to another deadly double shooting, this time at an apartment complex in the east bank Monday afternoon. The case is not related to the shooting near Westwego.

In the second homicide investigation, deputies responding to a disturbance at an apartment in the 5800 block of Walnut Creek Road in River Ridge found one woman dead and a man with non-fatal gunshot wounds to his hip and arm. No suspects or a motive have been identified in the case.
