It happened Thursday night at a vigil near Yellowstone Park in south Houston.
Houston police say they are looking for the person who pulled the trigger and fired off several shots killing Dexter August. Family and friends we spoke with Friday say the violence needs to stop.
"He had a gun in his back pocket, he pulled it out, shot him and killed him," said the victim's cousin, Joseph August.
Family and close friends of the 35-year-old August say they don't know why someone would shoot and kill anyone at a candlelight vigil being held for another victim of gun violence.
"It's hard, it's really hard. Like I said, he was like a brother to me," said Monique Alexander, a close friend of the victim.
Police say the shooting happened here in Nelson Park at around 9pm Thursday. About 200 to 300 people were in this area when the shots were fired. August's cousin told Eyewitness News her son was there and called her right after the shooting.
"Some kind of way they ended up fighting and the boy had a gun in his back," said Ginita Hill, the victim's cousin.
Police say after Dexter August was shot, the person who pulled the trigger took off. Alexander says she got worried after he never showed up to her house last night.
"Like I said, I had just talked to him and he told me he was fine. He was alright and he would see me later on," said Alexander.
Family told us they believe they know the name of the man who pulled the trigger and hope police are able to find him.
"I don't know how the community can come together and stop the violence. Please stop the violence," Hill said.
Police say the investigation is ongoing and they are now looking to a nearby house for more answers. It has several cameras, one possibly pointing in the direction of the park.
The memorial service was being held for a murder that happened on Tuesday. A man in his 20's was shot several times while inside his car and killed. Eyewitnesses tell police two men approached the vehicle and shot him. Robbery is believed to be the motive.
Police say it's still unclear if the two shootings are related. Anyone with information on either murder case is asked to call Crime Stoppers at 713-222-TIPS.
