Authorities in Texas are searching for an 18-year-old suspect linked to a fatal shooting involving a teenage girl during a party altercation. The individual, Deshawn Suggs, is being sought in connection with the murder of 17-year-old Alianna Ujueta, as reported by the Bexar County Sheriff’s Office in an announcement made on Thursday.

The tragic incident took place on September 28. Prior to the shooting, a social gathering was underway at a residence located on the 13000 block of Luckey Road in Atascosa, Texas. As the night progressed and the clock neared 2 a.m., a confrontation erupted, eventually moving outdoors. It was at this point that gunshots were fired, according to police reports.

Ujueta was fatally shot, and responding deputies discovered her with a gunshot wound to the head, lying on the street, as detailed by the sheriff’s office. A witness recounted seeing a dark-colored pickup truck drive over the victim before fleeing the scene, as reported by the San Antonio-based ABC affiliate KSAT.

Prior to the incident, people were gathered at a party at a home on the 13000 block of Luckey Road in Atascosa, Texas. At some point before 2 a.m., a fight broke out and spilled over into the street. Then “gunfire erupted,” authorities say.

Someone gunned down Ujueta, and when deputies responded to the scene, they found her lying in the street with a gunshot wound to the head, the sheriff’s office says.

A witness said that a dark pickup truck drove over the victim and then drove away from the area, according to San Antonio-based ABC affiliate KSAT.

Nearly two months later, authorities announced they believe Suggs is the one who killed the girl.

Law enforcement officers recovered multiple items at the scene of the shooting, including articles of clothing, jewelry, and spent shell casings, the San Antonio Express-News reported.

Authorities have not revealed how they honed in on Suggs as their suspect.

Suggs also faces other charges, according to the local newspaper, with one such charge coming from just about a week before the shooting.

Due to an incident on Sept. 19, the defendant was charged with unlawfully carrying a weapon. He also faces charges of burglary, robbery, and making a terroristic threat in a case dating back to February.

Ujueta’s older brother said his sister “would want to be remembered by the love that she had for her family.”

The victim’s older sister added, “We’re missing her. It’s really hard.”
