One man was killed and three others were wounded late Friday in a drive-by shooting at a park in Dallas' Oak Lawn neighborhood.

It was one of five deadly shootings in Dallas late Friday and early Saturday, the bloodiest night on record in Dallas in years.

The Oak Lawn shooting was reported about 9:15 p.m. at Cherrywood Park in the 5400 block of Maple Springs Road, police said.

Someone in a vehicle opened fire from the street, spraying a crowd on the basketball court at the park with bullets.

Two of the victims were taken to a hospital by Dallas Fire-Rescue paramedics, and the other two were driven there in private vehicles.

Alan Valdez, 20, died from his injuries at the hospital, police said.

Two of the survivors were listed as stable, while the condition of the third was unknown, KXAS-TV (NBC5) reports.

Investigators with the gang unit were called in, but a motive had yet to be determined. No suspects were in custody, police said.

Four other men were slain over the course of seven hours in the White Rock neighborhood and west, central and southeast Oak Cliff. Arrests were made in two of the shootings.

It was the busiest night for Dallas homicide detectives since five men were killed in a 24-hours span in late September 2016, police records indicate.

Police did not say whether any of the crimes were related, though some were believed to be gang-related.
