A spate of gun violence that plagued the city over the Memorial Day weekend continued Monday when four people were wounded and two were killed in five separate shooting incidents that began before sunrise.

At least 19 people were wounded or killed by gunfire in Orleans Parish between Friday night and Monday evening, with a 17-year-old male and an unknown man becoming the city’s most recent homicide victims.

The teenager, who was not immediately identified, was shot a little after 4 p.m. Monday at Eads and North Rocheblave streets, said Officer Hilal Williams, a Police Department spokeswoman. He died a short time later at the hospital.

An unidentified male was shot to death about 6:15 p.m. at Charbonnet and North Johnson streets in the Lower 9th Ward.

About 3 p.m., a man was shot while he rode his bicycle near North Claiborne Avenue and Gov. Nicholls Street.

A man got out of a Chevrolet Impala that pulled up to the victim and opened fire, Williams said. The gunman then hopped back in the car and sped away.

The victim was struck twice in the shoulder and had a graze wound to his face, Williams said. He was reported in stable condition at a local hospital.

Early Monday, police were called to investigate a shooting at South Roman and Perdido streets about 4 a.m.

The victims were inside a car at the corner when another vehicle pulled up and someone opened fire before speeding away.

One man was shot in the back, while two women in the vehicle suffered graze wounds to their arms and legs. None of the injuries were serious, Williams said.

A fourth person in the car was not hit, she said.

At least five people were shot across the city Sunday, including a 43-year-old man who died after he was struck in New Orleans East.

Clarence Wilson III was found on the ground at Chef Menteur Highway and America Street about 8 p.m.

Wilson died at Interim LSU Hospital from a gunshot wound to the head, said John Gagliano, the Orleans Parish coroner’s chief investigator.

Another person was shot about 8:20 p.m. in the 1400 block of North Claiborne Avenue, near Esplanade Avenue. Police did not provide any details about that shooting.

Earlier Sunday, three men were shot in the Fischer housing development in Algiers when someone opened fire on them, apparently with an assault rifle.

That shooting happened about 4:30 p.m. in the 1700 block of Hero Boulevard.

The victims ­— ages 19, 21 and 35 — were in stable condition at a local hospital after the shooting, police said.

Police said Monday they were searching for a white SUV that the gunman used to get to and from the scene of the Algiers shooting. Police did not identify the make and model of the SUV.

The weekend’s most stunning shooting happened late Friday night during a high school graduation party at a home in the 6200 block of Eads Street in Gentilly when eight people were wounded, one fatally.

Eyewitnesses said they heard between 15 and 20 shots about 11:20 p.m. A dispute among partygoers led to the gunfire, police said.

When the shooting ended, 15-year-old Tremaine Robertson of Spring, Texas, was among those struck. He died a short time later at Interim LSU Hospital.

The other shooting victims were four women and three men between the ages of 19 and 30.

Police have not announced any arrests or identified suspects in any of the cases.
