It happened at about 6:40 p.m. in the 1400 block of North Market Loop where Sgt. Greg Campbell said a mother was holding a vigil for her son, known as Lil' Daddy, who was killed at his home a couple of weeks ago.

Gonzalez said about 50 people, adults and children, were in attendance.
"While they were having their celebration of life and releasing balloons in the air, an unknown suspect drove down this road and shot rounds into that group of people," said Campbell.
In total, 14 people were shot. One woman, identified by deputies as Disha Allen, was pronounced dead at the hospital.
Three people were taken to the hospital by Life Flight, and the rest transported themselves to Houston Methodist Baytown Hospital to be treated for non-life-threatening injuries, according to Campbell.
ABC13 spoke with a witness at the vigil and said he heard about 20 to 30 gunshots.
"People were screaming and running to their cars," said Sidney Williams, the witness.
Once everyone started arriving at the hospital, another incident occurred.

"When everyone got to the hospital, a large fight ensued and we had to contact other agencies to help with that large fight," said Campbell.
Some of the victims were later transported to Memorial Hermann for the treatment of more serious gunshot wound injuries.
Initially, authorities said eight people had been shot, but Gonzalez held a briefing later that night and gave an updated number.

"Bullets don't have eyes, so it puts everyone at risk," said Gonzalez.
Witnesses told ABC13 two of the victims shot were the pastor and his wife who were in attendance at the vigil.
Authorities did not release the ages or identities of the rest of the victims, and did not say if any of them are children.
No arrests have been made. The sheriff's office said the suspect or suspects in the case are believed to have been driving a small, dark-colored sedan.
Anyone with information regarding the suspect(s) in this case is encouraged to call the Harris County Sheriff's Office Homicide Unit or Houston CrimeStoppers.
