MILWAUKEE (CBS 58) -- Attorney Michael Hupy is doubling the reward he's offered for information about a Milwaukee murder case. 

Community activist and rapper, Quanita "Tay" Jackson, was shot and killed on August 25 in a drive-by shooting near Moody Park on the city's north side. 

Milwaukee police are still searching for the person responsible for the shooting. 

Jackson had organized a basketball tournament at Moody Park a day before she was killed. 

Michael Hupy is on the board of directors of Children's Outing Association in Milwaukee, an organization Jackson worked with.

Hupy first offered a $25,000 reward, now he has increased it to $50,000. 

He hopes the money will encourage someone with information leading to an arrest and conviction to come forward.
