A Baton Rouge man who was shot Tuesday evening died at a hospital on Thursday, the same day investigators made an arrest in a different fatal shooting this week.

Kwemon Davis, 23, died after spending two days in critical condition following a Tuesday afternoon shooting in the 2200 block of Spanish Town Road, said Cpl. L’Jean McKneely, a Baton Rouge police spokesman.

McKneely said Davis was in a 2010 Mercury Milan at about 5:20 p.m. when two men in another vehicle began chasing Davis and shooting at him. Davis eventually was shot, and he ended up crashing his car into a utility pole near the intersection of North 22nd and Gracie streets.

McKneely said a motive for the killing wasn’t known on Thursday, and police did not have a suspect in Davis’ death.

Darren Ellis, Davis’ cousin, said Davis was a hard worker who worked a construction job in the Baton Rouge area.

“He was a good dude,” Ellis said.

Ellis, 23, said Davis’ death came about three years after Davis’ brother, Latrell Davis, was fatally shot during what police said was a drug deal on Gerald Street. The shooter, Nicholas Revish, now 24, was convicted last year of second-degree murder in Latrell Davis’ death and sentenced to life in prison.

Ellis said Latrell Davis died just before a daughter of his was born. After Latrell Davis’ death, Kwemon Davis stepped up to take care of his infant niece, Ellis said.

Both Ellis and Keon Preston, a chaplain with the Stop the Violence nonprofit group, said Kwemon Davis wasn’t the target of Tuesday evening’s shooting. There was another man in the car with him at the time of the shooting, they said.

Police have said Davis was the only person in the car at the time of the shooting.

Preston, the chaplain, said a memorial will be held for Davis at 6 p.m. Saturday where the crash occurred at the corner of North 22nd and Gracie streets.

The morning after Davis was shot, Lenroy Marshall, 46, was fatally shot outside a Lorna Avenue home in the Belaire neighborhood.

Baton Rouge police on Thursday arrested Jaime Mejia, 34, in Marshall’s death.

Mejia told police he shot Marshall because the 46-year-old was trying to rob him, according to a police report. Mejia also told detectives Marshall had previously robbed him.

In the report, police said Mejia’s version of Wednesday morning’s shooting was inconsistent with witness statements and other evidence gathered at the scene.

Mejia, of 12387 Lorna Ave., Baton Rouge, was booked into the East Baton Rouge Parish Prison on counts of second-degree murder and illegal use of a weapon. His bail was set at $265,000.
