Baltimore police say the man they believe responsible for stabbing a man with a broken bottle moments after the July 4 fireworks at the Inner Harbor has surrendered. From reporters Arthur Hirsch and Jessica Anderson:

Marcus Sterlin Harris, 32, turned himself in and was charged with first degree murder in connection with the fatal July 4 stabbing of 26-year-old Joseph Lorenzo Calo, who had been in town from Alabama visiting family. Both men were involved in a shoving match outside McCormick & Schmick's Seafood Restaurant on Pier 6, police said. Calo was later stabbed in the neck with a broken bottle.

Police provided few details nor a motive into the stabbing during a brief news conference Saturday at police headquarters, where Harris had turned himself in earlier. Police also had little information about a man who they said died after being stabbed in a fight at the corner of North Charles and Fayette streets around 1:30 a.m.

Lt. Col. Jesse Oden, chief of detectives, thanked the person who provided police with the photo of Harris taken during the incident, calling it "crucial evidence." He said "numerous people came forward with his identity" after police released the photo to news media.

Harris, whose latest address listed in court records was in the 400 block of Rosecroft Terrace in Baltimore, has a string of more than a dozen arrests, according to court records. Most of those arrests relate to drug and assault charges. In 2007 he received a three year prison sentence for drug distribution.
