A woman accused of fatally stabbing her older cousin during a fight in the French Quarter last week surrendered to New Orleans police on Monday.

Dannisha Green, 20, was booked with second-degree murder in the slaying of 22-year-old Brittany Seymour.

Police suspect that Green stabbed Seymour about 1:15 a.m. Thursday during a loud argument that began in the 200 block of Decatur Street and then escalated into a scuffle in the 300 block. Onlookers had broken up the fight when Seymour realized she had been stabbed, authorities said.

Seymour died at a hospital, and police a few hours later confirmed Green was wanted in her killing. Green remained at large until she turned herself over to investigators about 12:30 p.m. Monday, police said.

Police haven't publicly discussed a motive in Seymour's killing. But Seymour's mother, Kimi Seymour, said Brittany ran into Green while out celebrating her recent birthday at the House of Blues with her sister and a friend.

Kimi Seymour said she understood that her daughter and Green then started arguing over Seymour's ex-boyfriend, a topic that has long been a point of point of contention between the two. That argument led to the deadly fight, Kimi Seymour said.

Brittany Seymour attended St. Mary's Academy in New Orleans East and dreamed of becoming a nurse before she was killed.

The founder of the nonprofit Project NOLA security camera network captured footage of Green and Seymour beginning to argue on Decatur shortly before the stabbing, organization founder Bryan Lagarde said Monday.

The footage also showed the cousins walking toward the spot where the killing occurred, with a crowd of people following. Lagarde said he turned that video over to police investigators before they publicly said Green was wanted.  

There had been 10 people killed in seven separate incidents in June at the time Green surrendered. Her arrest is one of two that have been announced in those homicide cases.
