CYPRESS, Texas -- A massive house party advertised on Twitter turned violent when two people were shot and almost two dozen others were injured late Saturday in northwest Harris County, deputies said.
According to Harris County Sheriff's Office, the mass shooting happened at 11:30 p.m. in the 7300 block of Enchanted Creek Drive.
More than 100 people, mostly young adults, were at the scene when the gunfire started and many fled the home in a panicked rush to escape.
Deputies said a man and a woman were killed, while at least 22 others were injured during the shooting. One of the victims died at the scene, while another at Cypress Fairbanks Medical Center Hospital.
Injuries range from critical to minor, deputies said. Five area hospitals received the injured, some of whom were transported by emergency vehicles and others in their own vehicles.
A teenager who attended the party said gunshots began in the house and continued outside as people ran into the streets seeking cover.
Shaniqua Brown says Saturday evening's birthday party "was not rowdy at all," and many people were dancing when they heard the shots.
The 17-year-old Brown said she saw one gunman when she ran outside.
Pools of blood were visible outside the two-story brick home, and the garage door was bent after people had pushed it upward while trying to escape.
Harris County Sheriff Adrian Garcia said the gathering Saturday night that drew more than 100 people, most of them 17- to 19-year-olds, became a "birthday party gone wild."
He said it appears partygoers were dancing in the home when someone armed with a pistol shot into the air in celebration. In the ensuing confusion, another person who was armed began firing into the crowd, Garcia said. Young people then streamed into the narrow street to avoid the burst of gunshots that followed shortly before 11 p.m. Saturday.
Authorities have given varying accounts of the number of people injured, but they clarified Sunday that 20 were hurt, with 16 suffering gunshot wounds and four others varying injuries such as a fracture and twisted ankles in the panic to flee.
The two people killed, one an 18-year-old male and the other a 16-year-old female, were high school students in Cypress, Garcia said.
He chastised the party organizers, who advertised the event on social media, saying "you have no control on who to expect at your door."
"It's a horrible combination of immaturity, access to a firearm, and the inability to control one's self," he said.
Authorities are searching for two gunmen, he said, one who's about 17 years old and the other believed to be about 22.
