HOUSTON, Texas (KTRK) – The Mayor of Houston made it clear in a briefing Friday that the city will not be silent amid a historic wave of crime.

The violence this week is shocking. A total of five children were shot between Wednesday night and Thursday night.

Some children have been hit by stray gunfire and are recovering, while others were killed.

On Wednesday night, almost an entire family was murdered in the style of an execution in their apartment in southwest Houston.

Xavier Davis, 28, was arrested and charged with three counts of murder in connection with the shootings. He was arrested Thursday on an unrelated domestic violence charge.

The briefing began late Friday after members of the Carhee family unexpectedly showed up at City Hall. Officials spoke to them and invited them to take the stage with Mayor Sylvester Turner.

“We stand strongly here with these families and ask our community to do one thing – if we have children who are affected by violent crimes, please throw our hearts for their families,” said HPD boss Troy Finner.

Little Harmony Carhee, 6, and her parents Donyavia Lagway and Gregory Carhee were shot dead in their Fondren apartment shortly after 10:30 p.m. on Wednesday

Harmony’s 10-year-old sister was also shot, but she played dead during the rampage and then FaceTimed her grandmother to show her what happened after it was all over.

“She was strong. She was hurt. But my baby came out of nowhere in any way to make a difference,” said Grandmother Manda Lagway. “I just want everyone to know my baby is a hero. My baby is a hero. “

This little girl is going to need so much love and protection and help after seeing what she has seen. My heart goes out to the Carhee and Lagway families.

The 10-year-old was released from hospital on Friday and is recovering from her injuries. She told the police that the killer knocked on the apartment door before the rampage.

He was wearing a mask and grabbed her one-year-old little brother by the hair and threw him, the little girl told the police. He then shot the victims in the head.

She said she pretended to be dead and when the killer left she went to get her brother and locked the door.

“Your life has changed forever,” said Turner. “I just want to express my condolences and prayers to these families whose lives have changed in the last 48 hours.”

The 1-year-old was uninjured, said his family. The couple also have an 8-year-old son who spent the night of the shooting with his uncle.

A suspect in the shootout has been arrested, Turner said. The police are still looking for the second shooter.

“The one who is not in custody, I will not say your name, but you know who you are and we do too,” said Finner. “Adjust yourself and face him.”

Turner announced that the city has added six classes of cadet to HPD to increase the number of police on the streets.

“For people who walk and drive on our streets and shoot these guns as if they were BB guns, that’s totally unacceptable,” he said. “We’re going to do the overtime to protect the city.”
