A 12-year-old Greenwich boy reported missing has been found and he is safe, according to police.
Pierce Horton disappeared on Monday and has since been found.
In the past, Lt. Paul Vance, of Connecticut State Police, explained the difference between Amber Alerts and Silver Alerts.
Amber Alerts are issued when there is an "absolute emergency" involving a child under the age of 18 in which his or her life is in danger.
A Silver Alert is used for any child who is missing, missing people over the age of 65 and anyone other missing people who might have a medical condition requiring medication.
