A tip led police to posts they say showed knife threats before Tamar Shaw was fatally stabbed.
HARRISBURG, Pa. — Instagram videos allegedly showing a teenage girl with a knife near her boyfriend became a key part of a Harrisburg murder case after the boyfriend died from a chest wound, police said in charging documents.
The videos shifted the case beyond the first report of a man bleeding inside a home. Investigators said Dalaysia Terrell-Brown, 17, had described the stabbing as something she did not see happen, but later evidence raised new questions. Tamar Shaw, 18, died after police found him wounded on April 6 in the 1400 block of Market Street.
The first known call for help came late that Monday night. Police said dispatchers received a report that a man had been cut and was losing blood. Officers arrived around 10:52 p.m. and found Shaw in the kitchen. A bloody white towel was being held to his chest. Shaw was alive but in distress. He could not clearly tell officers what had happened, complained that he could not breathe and collapsed before he was taken to a hospital.
The first account from Terrell-Brown centered on a small kitchen knife and a bed. She told investigators that Shaw had asked for a knife to cut rolling papers for marijuana. She said the knife may have been lost in blankets or sheets. She also said she was on top of Shaw on the bed and moved the blankets when he yelled in pain. When he removed his shirt, blood began coming from the wound, according to the account police described.
Police said Terrell-Brown told them she and Shaw had argued earlier in the day, but she denied that they were arguing at the time he was hurt. That detail became part of a broader timeline detectives were trying to build. Officers recovered three knives from her room. At that point, police had Shaw’s wound, Terrell-Brown’s account, the knives and the fact that Shaw had died, but they did not yet have the public social media material that later shaped the case.
A tip the next morning brought investigators to Instagram posts. Police said one video showed a hand holding a knife and trying to stab toward Shaw, with a caption that included “lmaoo cut that wrist up.” Investigators said another video showed Terrell-Brown pointing a knife at Shaw and saying, “Shaw ain’t gonna do s***,” and “let this be a warning.” A third video allegedly showed a serrated knife being thrown onto or toward Shaw’s neck as he lay in bed.
Those clips mattered to police because they appeared to connect words, gestures, weapons and the same victim before the fatal injury. Investigators said knives seen in the videos appeared consistent with knives found in Terrell-Brown’s room. Police have not publicly said whether the videos show the actual fatal stabbing. The record described by authorities points to the videos as evidence of prior threats or handling of knives, not as a released recording of the moment Shaw received the chest wound.
The coroner’s finding added weight to the murder charge. Shaw’s death was ruled a homicide after an autopsy found that the stab wound entered his chest cavity. The injury required significant force, according to the coroner information cited in reports on the charging documents. That medical finding gave investigators a sharper picture of the injury than the first emergency report, which described a man losing blood from a cut.
The case now turns partly on how prosecutors use the videos and how the defense answers them. The posts may help prosecutors describe what happened before the wound. They may also become the subject of court arguments about timing, context, identity, chain of custody and what exactly the clips show. Authorities have not publicly released the full videos, their metadata or a complete timeline showing when each one was recorded and posted.
Dauphin County District Attorney Fran Chardo said the work continued after Terrell-Brown’s arrest. “These investigations don’t end with an arrest,” Chardo said. “We continue working to determine exactly what happened.” That statement points to the open questions still surrounding the case, including the exact sequence inside the home, whether anyone else witnessed the injury and how forensic testing may support or challenge the first accounts.
Terrell-Brown was arrested April 7. Harrisburg police announced charges of murder and possession of an instrument of crime. Court records also list a drug paraphernalia charge. A judge denied bail, and the docket listed the bail reason as a threat to society. The case is active in Dauphin County, where early hearings will test whether prosecutors have enough evidence to move the charges forward.
The killing also put attention on how quickly a private conflict can become public evidence. The videos were not found by police at the scene during the first response, according to the reported timeline. They surfaced after a tip. That means a person outside the investigation saw something online and directed police to it. The tip gave detectives material that may have otherwise been deleted, overlooked or found later through a warrant.
Neighbors reacted with concern after learning that both the accused and the victim were so young. One neighbor told local television, “It’s unfortunate. We have kids here, and for something like this to happen so close to home, it’s scary.” The comment reflected a common theme in early public reaction: disbelief that a dating relationship involving teenagers could end in a homicide charge inside a Harrisburg home.
Police have not publicly released a full list of witnesses, the complete contents of the videos or the results of all testing on the knives. The official record also does not show a final resolution of the charges. Terrell-Brown remains accused, and Shaw’s death remains the focus of an active prosecution.
The Instagram videos remain central to the public account, but the next court filings are expected to determine how much weight they carry alongside the physical evidence and Terrell-Brown’s statements.
