At about 8:30 p.m., SEM was let out to take a break at Fountain Park on Martin Luther King Blvd.
At 8:45, Officer Mancini left the area, believing SEM was in the back of the vehicle.
A short while later, it was discovered SEM was missing, and a search of Fountain Park was conducted. That search resumed Wednesday morning with the help of firefighters, city works and a helicopter from Lehigh Valley Hospital.
Police say, at around 11:00 AM Wednesday morning, they received information from the Lehigh County Humane Society, who said that a message was left on their answering machine indicating that a dog was found on Martin Luther King.
The people who found the dog left their name and phone number.
Christanal Muth, of Emmaus, told police she was driving on Martin Luther King Drive last night around 9:00 P.M. when she saw the dog in the area of 10th & Martin Luther King, and the dog looked confused.
The dog entered her car and she took it home.
Muth says, she left for work and took the dog to a friend's house, and notified the Humane Society that they found the dog.
Officers responded to a residence where the dog was being kept, which is located in Salisbury Township. The dog was reunited with his handler.
