(CNN) -- Six people are dead and four others are injured after a birthday party shooting at a Texas skating rink.

Officers responded to the Roller World skating rink in Grand Prairie Saturday evening and found six people dead at the scene, Grand Prairie Police Chief Steve Dye said. Dye said one of those was the shooter, who appears to have died from a self-inflicted gunshot wound. The four injured were taken to local hospitals.

Police said the shooting happened during a private birthday party, and one witness told detectives on the scene that the alleged shooter was the guest of honor celebrating his birthday.

While the investigation is ongoing, the shooting appears to have stemmed from a domestic dispute between a husband and wife, Dye said.
