The search is intensifying for the person who opened fire at a graduation party in the Bronx, killing a 19-year-old girl and injuring three others.

It has been about two weeks since someone gunned down several people inside Shoelace Park, while they were celebrating a graduation.

The NYPD has released new surveillance video of a man wanted for questioning in connection to the death of Tyanna Johnson. The man is seen running down the street and later taking off what appears to be gloves.

The shooting happened on June 12 as 19-year-old Johnson was celebrating her college graduation inside Shoelace Park, when at around 11 p.m. she and three other males were gunned down. News 12 is told Johnson was shot five times and tragically died at the hospital. The three other victims have since recovered.

Detectives are working to piece together what lead up to this deadly shooting. Officials say Johnson was not the intended target.

Authorities are now offering up to $10,000 for information that leads them to the person who pulled the trigger.
