• A cousin of the Uvalde school shooter threatened to "do the same thing," his mom told police.
• His mother called police, saying her son had threatened to shoot his sister and a nearby school.

The Uvalde school shooter's teenage cousin tried to illegally get an AR-15 rifle and threatened to "do the same thing" as his cousin, his mother told police.

The San Antonio Police Department arrested the 17-year-old on Monday and charged him with one felony and one misdemeanor count of making terroristic threats against a public place and a family member, CNN reported.

According to an arrest warrant viewed by The New York Times, the teen had threatened to shoot his sister in the head and to "shoot the school." The family lives across the street from an elementary school, the Times reported, citing the arrest warrant.

The teen denied making threats against the school or his sister, The Times reported, citing the warrant. His lawyer, Jacqueline Lamerson, declined to comment on the case.

The teen's mother told police that her son told his sister that he wanted to "do the same thing" as his cousin, who killed 19 students and two teachers at Robb Elementary School in Uvalde, Texas, in May 2022, according to the affidavit seen by The Times.

The teen's sister told their mother about his statements, and the mother called the police, local outlet Fox29 reported.

His mother also told police she had overheard her son on the phone trying to buy an AR-15 rifle through "an illegal private sale," the warrant said, according to The New York Times.

The San Antonio Police Department did not immediately respond to Insider's request for comment.
