David Hidalgo was turned in to the TCU Police by his mother for stabbing TCU senior Stewart Trese, according to an arrest warrant affidavit released Wednesday. 

According to the affidavit, Sandra Cordona, Hidalgo’s mother, walked into the TCU Police Department on Feb. 4 and reported that her son told her he had stabbed someone that morning. 

Hidalgo told his mother that Trese had attacked him with a knife and that he took the knife away from Trese and cut him with it, according to the affidavit. During a jailhouse interview with WFAA, Hidalgo said Trese made sexual advances toward him. 

Police searched Hidalgo’s home and found bloody clothing and a bloody knife, according to the affidavit, filed by Fort Worth police detective J.T. Rhoden.

Trese’s father, Thomas Trese, along with a Grand Marc employee and a TCU Police officer, found Trese dead in his apartment after his father requested a welfare check on the morning of Feb. 4, according to the affidavit.

The affidavit said Trese’s father entered the apartment and found his son lying in the hallway.

Fairness Fort Worth, the education and advocacy organization for the lesbian, gay, bisexual and transgender (LGBT) community, released a press statement Thursday morning regarding Trese’s death and Hidalgo’s account of events. 

“Hidalgo has employed the widely dismissed ‘gay panic defense’ by which someone accused of committing a violent crime excuses their act as a response to an unwelcome sexual advance,” the release said. 

Hidalgo was charged with murder and is in Tarrant County jail on $100,000 bond. Hidalgo is scheduled for an initial appearance in Tarrant County District Court on Feb.14.
