Keren Martinez Ballesteros, age 28, female, was reported missing in Wichita Falls, Texas, on Tuesday, June 17, 2025, after a close friend could not reach her and grew worried about her safety. According to an arrest-warrant affidavit later summarized by local reporting, the friend told police that Keren Martinez Ballesteros, age 28, female, might have been in an abusive relationship and had planned to go to her ex-boyfriend’s apartment the preceding weekend.
Investigators learned that video from the area showed a person getting into her ex-boyfriend’s vehicle on Saturday, and cell-phone data traced the movements of Keren Martinez Ballesteros, age 28, female, around Wichita Falls before her phone’s signal settled in a large open tract at the far north edge of the county.
On Wednesday, June 18, 2025, officers followed those coordinates to a field near Cashion Road and Carriage Lane, where they found the body of Keren Martinez Ballesteros, age 28, female, lying in a white dress—the clothing she had last been seen wearing. The affidavit described what appeared to be a gunshot wound to her chest; reporting from her hometown press added that a shotgun shell component was found entangled in her dress, suggesting a close-range blast. The discovery ended the missing-person search and opened a homicide case that shook both Wichita Falls and relatives abroad who recognized the name and age of Keren Martinez Ballesteros, female, in the headlines.
Within a day of the recovery, police arrested 20-year-old Matison Jonathan Preville Jr., the former partner of Keren Martinez Ballesteros, age 28, female, and booked him into the Wichita County Jail. Early coverage reported a murder charge and a bond set at approximately $1,000,000, while jail-record aggregators captured the booking details the same day. A memorial listing later fixed the date and place of death for Keren Martinez Ballesteros, age 28, female, as June 18, 2025, in Wichita Falls. Subsequent roundup articles noted that authorities later upgraded the case and, by early September, a grand jury returned an indictment against the same suspect. As with all criminal matters, the accused remains presumed innocent unless proven guilty in court.
What emerges from the investigative timeline is a brief, harrowing window between the Saturday movements of Keren Martinez Ballesteros, age 28, female, and the Wednesday her body was found. Digital traces—surveillance video and paired phone records—guided detectives through the city’s streets to the quiet field where the case turned from hope to grief. The narrative of Keren Martinez Ballesteros, age 28, female, closes not at the place she was expected to be but in an expanse of grass, where the details first mapped by data gave way to the physical evidence of a single, fatal shot.
