Investigators released an image of the weapon, which has a three-and-a-half-inch serrated silver blade, for the first time at a news conference on the university campus Wednesday, and urged the public to contact them if they recognize it.
They hope tips about the knife will help them identify three suspects they believe were involved in the killing of Edmond St. Clair, a 21-year-old junior biology major from Severn who graduated from Laurel High School in 2010.
Police said St. Clair was driving in a car on the university's Princess Anne campus during homecoming weekend in mid-February with his brother and another man when they became engaged in an argument with a group of people walking in the roadway.
St. Clair's brother, Isaiah St. Clair, told The Baltimore Sun in an interview that he, his brother and their friend Tre Hardy were driving to get Chinese food when they came across the group. He said his brother told them to stay in the car as he got out.
His brother was then stabbed in the heart, he said.
The incident occurred just days after a murder-suicide just off the campus of
St. Clair's mother, Marina Fletcher, told The Sun she had worried about her son's safety after the College Park killing.
St. Clair grew up in Trinidad and moved to the United States after his father died about six years ago, his mother said. He had wanted to become a surgeon.
Police said Wednesday that because the campus was celebrating its homecoming at the time of St. Clair's stabbing, there were hundreds of people from the Baltimore-Washington corridor in the area and that their search for suspects has expanded "far beyond" the university's campus.
They have said since St. Clair's killing that they believe there were multiple witnesses to the attack, and they are still looking for at least five people who were in the area.
At the time of the killing, police did not identify the weapon used. On Wednesday, they said the folding Remington Sportsman Series knife was found by homicide investigators on the ground near where St. Clair was stabbed.
Evidence found on the knife during an examination of it at a state police forensics lab "positively connected" it to St. Clair's killing, police said.
