An 18-year-old Indianapolis man is headed to jail after prosecutors say a string of violent social media threats against Center Grove High School in February sparked an overnight investigation, emptied classrooms, and cranked campus security to high alert. What started as ominous messages swirling around student protest rumors ended in a Johnson County courtroom with a criminal sentence in July.
Adrian Abundio-Valente admitted to the threats at his sentencing and received one year in jail plus 545 days of active probation, according to prosecutors. Court records and filings outline additional conditions, including treatment and reporting requirements. The plea and sentence were entered on July 20, as first reported by WTHR.
Messages That Set Off Alarm Bells
Court papers and local coverage show the school received multiple direct messages threatening mass violence and demanding that the campus be shut down. One message warned, “I’m walking in tomorrow with a ARP and I’m killing everyone that's in my sight,” a line that quickly circulated among students and staff and sent anxiety through the Center Grove community. Hoodline reviewed the initial February reporting and school statements describing how the threats spread on Instagram and triggered the school’s emergency response.
How Police Traced the Posts
Investigators pulled records from Meta and used account data, including GPS coordinates and an IP address, that they say led them to a home on Indianapolis’ east side. Officers executed a search warrant at a residence in the 9100 block of Breen Court, where they seized electronic devices and a Glock 19, according to authorities. The investigation drew in multiple agencies: IMPD, the Johnson County Sheriff’s Office, Indiana State Police, and Center Grove Police, as detailed by WRTV.
Sentence, Conditions and the Prosecutor's Response
Prosecutors say the threats had very real fallout. Filings indicate roughly 1,000 students stayed home the next day while officials worked to secure the building. Johnson County Prosecutor Lance Hamner said his office moved aggressively to hold the sender accountable, stating, “We will not tolerate criminals from Indianapolis—or anywhere else—using threats and intimidation to terrorize the citizens of Johnson County.” The sentencing terms include a required mental health evaluation and moral reconation therapy, details laid out in court documents and reporting by WTHR.
School Response and Community Context
In the immediate aftermath, Center Grove officials and law enforcement boosted their presence on and around campus. The increased security coincided with planned student demonstrations: an anti-ICE walkout and a rumored pro-ICE counter-protest. Those demonstrations ultimately went forward without reported violence, with coverage at the time noting a brief, peaceful action and a heavy officer presence. Early reporting on the arrest and campus precautions came from Indiana Public Media and other local outlets.
