The 82-year-old Terrytown man pushed down during an argument-turned-robbery with a father and his adult son lay there on the ground for about an hour with a head injury, unable to help himself up until a passerby gave him a hand, according to the Jefferson Parish Sheriff's Office.

Though Robert James seemed fine by the time he spoke with deputies to report the New Year's Eve assault, the head injury had actually caused a brain bleed that was silently killing him, authorities said. James was found dead inside his apartment the next day.

Jefferson Parish Sheriff Joseph Lopinto late Monday announced the arrests of the two men accused of accosting James behind the Terrytown bar where the 82-year-old worked.

Rickey Lincoln Sr., 40, and Rickey Lincoln Jr. 21, both of Terrytown, were booked Monday with second-degree murder, simple robbery and obstruction of justice.

The Lincolns were identified through a Crimestoppers tip called in within hours after detectives released surveillance photos and a video of two men identified as "persons of interest" in the investigation.

The robbery occurred about 6:30 a.m. as James was taking trash to a dumpster located behind his place of employment, the Roaring 20's bar in the 400 block of Terry Parkway on Dec. 31.

James told deputies two men walked up to him and asked why he was in back of the bar, according to the Sheriff's Office. James informed the men that he worked there, but the pair began taunting him, telling him they'd never seen him before.

James threatened to call 911, prompting the two men to start walking away. But they suddenly turned around and began arguing with James, according to authorities.

When James pulled out his cell phone to dial for help, one of the men, described as the taller of the two, grabbed the phone and pushed him to the ground, according to the Sheriff's Office.

The men took off with the cell phone, leaving James on the ground. Because of his age and immobility, James couldn't get up on his own, authorities said.

He lay there for about an hour until someone walking by spotted him and helped up back inside. James called the Sheriff's Office to report the robbery about 10:30 a.m., after he composed himself and contacted relatives, authorities said.

He told the responding deputy he wasn't injured and refused medical treatment, the Sheriff's Office said.

But James was unaware that he'd actually suffered what became a fatal injury because it was untreated. A relative discovered James lying dead on a bed inside his apartment on the afternoon of Jan. 1 after family members couldn't get in touch with him, authorities said.

An autopsy determined James suffered a subdural hematoma, bleeding on the brain, said Jefferson Parish Coroner Gerry Cvitanovich, who noted that it's not uncommon for adults with such an injury to have no symptoms in the beginning.

Relatives told investigators James was joking and in good spirits in the hours after the robbery. They last spoke with him about 1:30 p.m. on Dec. 31, the Sheriff's Office said.

Rickey Lincoln Sr. and his son were being held without bond Tuesday at the Jefferson Parish Correctional Center in Gretna.
