Early Tuesday morning, a little after sunrise, a 15-year-old boy lost his life on a desolate, overgrown corner in Desire. Two hours later, police found a woman’s body in a vacant lot on the edge of Treme.

Both had been fatally shot.

After a recent spate of gun violence in the city, their slayings brought the city’s homicide total so far this year to 122, according to New Orleans police, compared with 121 at this time last year.

There were 155 people killed in New Orleans last year, according to police records.

Tuesday’s teenage victim was identified as George Carter.

Police found his body about 7 a.m. in the 3500 block of Piety Street, a stretch of asphalt next to a vacant lot where the former Desire housing development once stood.

Carter was pronounced dead at the scene from a gunshot wound to the head, according to police.

Homicide detectives were called to their next scene about 9:15 a.m. in response to a report of a woman lying in a vacant lot in the 800 block of North Derbigny Street.

She also was pronounced dead on the scene. Her identity was not immediately available.

Neighbors who live in the area said they heard no gunshots overnight and wondered if the woman might have been dumped in the lot.

Tuesday’s killings followed two unrelated shootings late Monday night.

A man was shot in the leg about 10:30 p.m. in the 6100 block of North Claiborne Avenue.

A second man was shot about 11:30 p.m. in the 1000 block of Lizardi Street in the Lower 9th Ward. He was in critical condition, according to a daily police log.

Police have not identified a suspect or motive in any of the cases.
