State wants to certify Lamar HS murder suspect as adult

HOUSTON, Texas (KTRK) -- A teenager who walked with a classmate when he was shot and killed near the Lamar High School campus is awaiting a court's decision on whether she'll be tried as an adult for murder.

The teen, whose identity is being withheld because she is a juvenile, is accused of luring DeLindsey Mack and another girl outside of Lamar High School as part of a coordinated attack. Mack was shot to death near the school in November 2018.

The teen was arrested in August 2019 on a murder charge.

On Thursday, prosecutors presented multiple witnesses and social media evidence in their efforts to get the girl certified as an adult.

According to investigators, the teen suspect and another girl were walking along Bammel Lane with the 18-year-old Mack during the school's first lunch period.

However, the teen suspect made an excuse that she had to go back to class halfway during the walk.

Police say moments later, a vehicle approached the group and opened fire, killing Mack. The other girl, who is not facing charges, was grazed by a bullet.

Police were looking into gang connections in the killing. A detective testified in court that Mack, who had connections with the YSB gang, liked the teen suspect. The detective also said she pretended to be interested in him, but she was dating a teen in the rival 103 gang.

In Twitter posts shortly after Mack's death, the girl said, " She handled her business & don't ever tell."

The teen was the third person charged in connection with Mack's murder.

Dave'on Thomas, 18, was arrested and charged with murder last May. Kendrick Johnson was arrested last March.

After Johnson was arrested, the girl's mom would take her to the jail where he was held to visit him, according to investigators.

According to the girl's Twitter account, she would post about "busting him out" of jail.

Detectives also detailed a number of other social media posts by the girl that they said shows her connection and loyalty to the 103 gang.

The hearing resumes Friday morning.
