The 23-year-old Anne Arundel County man charged with fatally stabbing a University of Maryland student early Sunday was ordered held without bond yesterday by a Prince George's County District Court judge.

After a brief hearing, Judge Thurman H. Rhodes denied a request by the attorney for Quan L. Davis that Davis be released on home detention until his next hearing.

Defense attorney Shawn Larson told Rhodes that Davis, who did not enter a plea yesterday, "steadfastly maintains his innocence on these charges." Davis is charged with first-degree murder in the stabbing death of Brandon J. Malstrom, 20, a sophomore on the College Park campus, who was killed in a scuffle outside a party.

Larson argued that there is nothing in Davis's background to suggest he would be dangerous if released pending trial. Larson said Davis, who played basketball and football at Oakland Mills High School in Howard County, won several awards in high school for his athletic and scholastic achievements.

Davis is a student at Anne Arundel Community College, where he is two classes shy of earning an associate's degree, Larson said. Davis is taking this semester off to work at a satellite TV company, Larson said.

In urging Rhodes to keep Davis incarcerated without bond, Assistant State's Attorney Fran Longwell said a witness saw Davis reach into his waistband and pull something out moments before Malstrom was stabbed. Police investigators are still looking for the murder weapon.

Longwell said Davis and his co-defendant, John Ryan Schlamp, 24, came to the University of Maryland campus area Saturday night to attend a party. When that party broke up, Schlamp and Davis crashed another party near the campus, Longwell said.

The trouble began when the two defendants were kicked out of that second party, Longwell said. "They were arrogant and upset they were told to leave the party," Longwell said.

Detectives allege that Malstrom and his brother, Bill, were standing in the 7300 block of Dickenson Avenue, outside the house where Schlamp and Davis had been ejected from the party, when the defendants confronted them.

According to police charging documents, Schlamp asked Malstrom for his cell phone. When Malstrom refused to hand it over, he was beaten and stabbed, according to charging documents.

Schlamp was apprehended at the scene of the attack Sunday and later identified Davis as having been involved in the altercation, police said. They said a witness saw Davis pull something from his waistband and strike Malstrom.

Davis's parents, grandparents and aunt were at yesterday's hearing. They declined to comment.
