A mistrial was declared Friday in the case of a teenager accused of fatally stabbing another teen during a fight after the Baltimore Ravens' Super Bowl parade in 2013.
Jurors had deliberated for about a day before deciding they could not reach a verdict.
James Johnston, attorney for defendant Nazr Williams, 17, said 11 jurors wanted to acquit Williams while one believed he should be found guilty.
Prosecutors said Williams stabbed three people in a melee on Howard Street downtown, as the victims left the Ravens victory celebration on Feb. 5, 2013. Deontae Smith, 15, died after suffering four stab wounds.
Smith's grandmother, Sharon Price, said she thought prosecutors presented enough evidence to convict.
One trial "was hard enough — I really want it to be over," she said outside the courtroom Friday.
A new trial was scheduled for April.
"At this point, the state still intends to prosecute Mr. Williams," said Baltimore State's Attorney Marilyn J. Mosby, who said prosecutors have remained in "constant communication" with Smith's family.
According to testimony, city homicide detectives had no suspects until five months after the killing, when they got a call from authorities in Western Maryland who said a teenager at a juvenile detention facility had information about the case. The teen said he was part of the fight and identified Williams — who was being held at the same juvenile facility — as the killer.

The teen and Williams had previously fought as students at Patterson High School, and the teen contacted police after the two got into another fight at the Savage Mountain Youth Center in Garrett County. He said the other victims did not know Williams.
The teen, Darius Miller, was reluctant to testify but was given immunity and ordered to testify by Circuit Court for Baltimore City Judge Alfred Nance.
He was the only witness. Assistant State's Attorney Angela Diehl told jurors in opening statements that one witness was enough.
But Johnston, Williams' attorney, said police failed to check cameras in the wired downtown business area beyond two city-controlled cameras, and questioned why police didn't perform forensic tests on blood and clothing recovered at the scene. He also said Miller had an "ax to grind" when he came forward.
