Instagram clips show 17-year-old girl’s threats with knife before her boyfriend was stabbed say police

Court records show Dalaysia Terrell-Brown was denied bail after Tamar Shaw died from a chest wound.

HARRISBURG, Pa. — In Pennsylvania, a 17-year-old girl charged in the fatal stabbing of her boyfriend was ordered held without bail after Harrisburg police accused her of killing him during an incident that began inside a Market Street home.

The criminal case against Dalaysia Terrell-Brown began April 7, one day after police said 18-year-old Tamar Shaw was found bleeding in the 1400 block of Market Street. The docket lists murder, possession of an instrument of crime and use or possession of drug paraphernalia. A judge denied bail, citing a threat to society.

The court record gives the case its formal frame, but the allegations start with an emergency response. Officers were called late April 6 for a report that a man had been cut and was losing blood. When they entered the home, Shaw was in the kitchen with a bloody white towel pressed to his chest. Police said he was unable to clearly explain what happened. He said he could not breathe, fell to the floor and was taken to a hospital, where he died.

The Dauphin County Coroner’s Office later ruled Shaw’s death a homicide. The wound entered the chest cavity and required significant force, according to the medical finding cited in reports on the affidavit. That detail is likely to matter as the case moves forward because it addresses the nature of the injury, not just the fact that a knife was present. It also helps prosecutors argue that the wound was not a simple surface cut.

Terrell-Brown gave police an account that placed Shaw, a knife and bedding together before the injury. She said Shaw had asked for a small kitchen knife to cut rolling papers for marijuana. She told investigators the knife may have become wrapped in blankets or sheets. She said she moved blankets while sitting on or near him, then he yelled in pain. She said she did not see the precise moment he was hurt.

Police said she also told them the two had argued earlier in the day. She said the argument had ended before Shaw was wounded. That part of her statement gives investigators a possible motive question but not a complete answer. The public record does not say what the earlier argument was about, how long it lasted, whether anyone else heard it or whether police recovered messages that might explain it.

The legal stakes rose after investigators learned of videos allegedly posted to Instagram before the stabbing. Police said a tip directed them to the posts the next morning. One video allegedly showed a hand with a knife moving toward Shaw and included a caption about cutting a wrist. Another allegedly showed Terrell-Brown pointing a knife at Shaw and saying, “let this be a warning.” A third allegedly showed a serrated knife being thrown toward Shaw’s neck while he was in bed.

The videos may become some of the most contested evidence in the case. Prosecutors can argue they show threats and knife handling before the fatal wound. A defense lawyer could question timing, context, whether the clips were meant as threats, whether they show the same knives and whether they prove intent at the later moment Shaw was injured. Police said knives seen in the videos appeared consistent with knives recovered from Terrell-Brown’s room, but public reports do not include final forensic results.

Harrisburg police announced the arrest in a public posting, saying Terrell-Brown was charged in a homicide investigation that began April 6 in the 1400 block of Market Street. The posting identified her as 17 and listed murder and possession of an instrument of crime. It also noted the presumption of innocence. That point remains important because the charges are allegations, and the case has not reached trial or a plea resolution.

Dauphin County District Attorney Fran Chardo said investigators were still working after the arrest. “These investigations don’t end with an arrest,” Chardo said. “We continue working to determine exactly what happened.” His statement signals that prosecutors may still rely on additional interviews, medical records, forensic testing, digital records and witness accounts before deciding how to present the case in later proceedings.

The court process is expected to examine whether prosecutors can show enough evidence for the charges to proceed beyond the early stage. In a preliminary hearing, the government does not have to prove guilt beyond a reasonable doubt. It must show enough evidence that a crime occurred and that the defendant is probably connected to it. The defense can challenge parts of that showing, including witness testimony and the interpretation of physical or digital evidence.

The drug paraphernalia charge reflects the account involving rolling papers and marijuana, but it is not the center of the case. The main charge is murder, and the instrument charge focuses on the alleged use or possession of a knife with criminal intent. The docket lists the offense date as April 6 and the arrest date as April 7. The case is listed as active, with the Harrisburg Police Department named as the arresting agency.

Outside court, the case has unsettled people near the Market Street home. A neighbor told local television that the violence was frightening because children live nearby. “They’re so young to even be in this type of situation,” the neighbor said. That reaction adds a human frame to the court file: an 18-year-old is dead, a 17-year-old faces a murder charge and a neighborhood is left with the memory of emergency vehicles at a home late at night.

Many details remain unknown. Police have not publicly released a complete second-by-second timeline of the incident. They have not said whether Shaw made any final clear statement about who stabbed him. They have not released the full videos, all forensic findings or the complete affidavit text in a way that answers every question about intent and movement inside the room.

Terrell-Brown remains accused in an active Dauphin County case, while Shaw’s death remains classified as a homicide. The next phase belongs to hearings, motions and evidence review before any trial decision.
