Jasper, Texas - Nine teenagers were wounded in a shooting at a prom after-party in east Texas early Sunday morning.

Gunfire erupted shortly after midnight at a home in Jasper, police said. All nine victims suffered injuries not considered life-threatening, the Jasper County Sheriff’s Office said. No suspects were immediately arrested.

"This investigation is ongoing and people of interest are being questioned," the sheriff’s office wrote on Facebook.

The teens were gathered after prom in Jasper, about 115 miles northeast of Houston, according to police.

All nine victims were between 15 and 19 years old, police told local ABC affiliate KMBT.

While most victims were treated at a Jasper hospital, some were transported about 60 miles south to a hospital in Beaumont.

The shooting happened one week after four people were killed and 32 others wounded in a shooting at a 16th birthday party in Alabama.

Five people have been arrested in connection with that shooting, with police making the fourth and fifth arrests on Thursday.

Police have not publicly speculated on a motive in either shooting.

Multiple attendees at the Alabama party were worried about potential violence before the shooting started. Early in the night, the mother of birthday girl Alexis Dowdell asked anyone with a gun to leave the building, according to multiple witnesses.

One of the victims, 23-year-old Corbin Holston, only arrived at the party after one of his younger siblings feared trouble, Holston’s family told local media.
