Police Commissioner Ray Kelly drew attention Tuesday to the missing child case of Patrick Alford, who was last seen in Brooklyn in January 2010.
During a news conference, Kelly held up a picture of the boy, who was seven years old when he disappeared from his East New York foster care home.
The commissioner said the New York City Police Department has received more than 50 tips about this case, all of which have been investigated.
Alford was four-feet-eight-inches tall and weighed about 65 pounds at the time he vanished.
The NYPD says there is a $12,000 reward for anyone with information about the case.
Anyone with information on the case should contact the Crime Stoppers hotline at 1-800-577-TIPS, or text CRIMES and then enter TIP577, or visit www.nypdcrimestoppers.com.
