Police Respond to Seven Discharged Firearms Calls and Arrest Two over Weekend


The San Marcos Police Department responded to seven separate discharged firearms calls between Saturday, Oct. 10 at 9 p.m. and Sunday, Oct. 11 at 5 a.m. Most incidents occurred at large parties with one resulting in the arrest of two individuals.


Brown and Mathis-MugshotsTyrian Kier Brown (10/16/96) of Glenn Heights, TX, was arrested for Deadly Conduct and Tamper/Fabricate Physical Evidence while his brother Broderick Taray Mathis (02/09/1993) of San Marcos, TX, was arrested for Assault Family Violence and Criminal Mischief.


On Sunday at approximately 1:08 a.m., SMPD was dispatched to building 5 at The Cedars, 1101 Leah Avenue, in response to multiple calls of shots being fired and people screaming and yelling. After investigating, officers determined that Tyrian Brown was involved in a physical altercation with his brother Broderick Mathis when Brown produced a .380 pistol and fired twice into the air.

Brown then hid the weapon in the parking lot under an uninvolved vehicle and picked up one of the shell casings while his brother punched the rear window out of a nearby SUV.  

Brown and Mathis were transported to the Hays County Jail for booking and magistrate with Brown posting a $10,000 bond and Mathis being released on his own recognizance.

Public Help Requested

SMPD is asking the public for help in identifying any of the suspects involved in the remaining six weekend discharge of firearms calls.  These acts appear to be a new “fad” among partygoers in San Marcos; however, knowingly discharging a firearm at or in the direction of one or more individuals or a habitation, building or vehicle that is occupied is considered Deadly Conduct, a third-degree felony.  If convicted this charge could result in a $10,000 fine and up to 10 years of jail time and/or probation for the offender.


Anyone with information regarding any of these incidents is asked to call the SMPD Criminal Investigations Division at 512.753.2300.
