BROOKLYN - A judge has thrown out the murder convictions of three half-brothers as it reviews cases closed by a retired Brooklyn detective. 

Alvena Jennette, Robert Hill and Darryl Austin were found guilty based on evidence collected by former detective Louis Scarcella. Austin died in prison 14 years ago. 

Scarcella's work first came into question last year when a judge threw out another man's conviction in the 1990 murder of a Brooklyn rabbi. 

The Brooklyn District Attorney's Office said it's reopening about 50 of Scarcella's cases. He denies any wrongdoing.
