Investigators say the scene on Colcord Avenue offered immediate physical clues after a woman reported being stabbed by her live-in boyfriend.
WACO, Texas — The first public details in the case against Joe Herrera come less from sweeping claims than from a compact set of scene evidence: a 911 stabbing call, a broken front window, blood on Herrera’s shirt and injuries officers said matched the victim’s account.
Police say those details support an aggravated assault family violence charge against the 39-year-old after a March 3 incident at a home on Colcord Avenue. The documents released so far matter because they show how investigators are building the case from what they found at the house and from what Herrera and the woman each told officers in the first minutes after the confrontation.
The sequence began, according to the affidavit, when officers were dispatched to investigate an active disturbance after a 911 caller reported someone had been stabbed with a knife. By the time police reached the house, a large window at the front had been broken out. Herrera was standing in the front yard with blood on his shirt, investigators said. Inside, the woman told officers that Herrera had stabbed, or “stuck,” her in the chest multiple times with the tip of a paring knife before she was able to lock him outside. Officers noted visible injuries consistent with what she described and photographed them. Police also estimated the violence occurred roughly two to five minutes before Herrera was shut out, a narrow time frame that suggests the physical scene had not materially changed before officers arrived.
From there, the affidavit turns on competing explanations for the same scene. Herrera allegedly told police he was trying to force his way back into the residence because he had seen his girlfriend naked inside with a man he did not recognize. He admitted breaking the window and said he then saw an unknown Black man flee the house on foot. Investigators said they found no evidence that another man had been inside. Their account instead was that Herrera apparently saw the woman without pants through the window and decided, without corroboration, that she must have been with someone else. That clash between claim and evidence is likely to become a central issue if the case proceeds: prosecutors can point to the lack of support for Herrera’s story, while the defense, if it contests the charge, may try to test how thoroughly the scene was processed and how quickly officers made their judgment.
The affidavit adds another layer by describing the alleged motive as part of an established pattern. Detectives wrote that Herrera “seems to be fixated” on the idea that his girlfriend is cheating on him. Police said they learned many of the couple’s arguments involved Herrera wanting to go through her cellphone and objecting to her leaving without his knowledge. Those details do not function as scene evidence in the same way as broken glass or photographed injuries, but they help explain why investigators interpreted Herrera’s statements as paranoia rather than a credible report of an intruder. They also provide early context for a domestic violence framework in which suspicion and control often become central to how police and prosecutors describe escalating harm.
The available public record does not answer several practical questions. It does not say whether neighbors heard yelling before the 911 call, whether any surveillance footage exists, whether the knife was recovered at the house or whether the woman required extended hospitalization. It also does not say whether prosecutors plan to seek more severe charges or additional allegations. What the record does show is that Herrera’s prior history may remain relevant. A detective wrote that he has past domestic violence convictions, and a 2025 Texas appellate opinion separately documented earlier convictions involving family violence in McLennan County. In that prior case, the court upheld concurrent 40-year sentences after testimony that Herrera assaulted Marisa Espinoza during a 2022 dispute and later admitted from jail that he grabbed her by the neck.
That combination of fresh scene evidence and older court history may define how the case is understood in the weeks ahead. On one side is the immediate picture officers described on March 3: an injured woman, a damaged window and a suspect with blood on his shirt. On the other is a larger legal context that already tied Herrera’s name to prior family-violence convictions before this arrest. Together, those facts give the case both a narrow physical record and a broader narrative of repeated allegations involving intimate partners.
Herrera was booked into the McLennan County Jail on $20,000 bond, according to the initial report, and he was later no longer listed on the jail roster. The next public checkpoint was expected to be a formal docket entry, court appearance or charging update that would show how McLennan County prosecutors intend to press the case.
