The reward to catch the person or persons responsible for breaking into a Macon animal shelter last week has swelled to $18,000.
The Atlanta Humane Society announced Thursday that it's chipping in $5,000 for any information leading to an arrest and conviction related to the crime.
That reward is on top of $5,000 from the Humane Society of the United States and $5,000 from People for the Ethical Treatment of Animals.
Macon Regional Crimestoppers is offering $3,000.
All About Animals, 101 Riverside Drive, Macon, was broken into Oct. 17. Three dogs were killed and 15 were injured.
Macon police said several cages were opened, freeing about 40 dogs, and many of the dogs had bite marks and lacerations.
According to an email from Macon Police, PETA representatives had stated some of the animals appeared to have stab wounds. Police do not believe that to be the case, and think all the animals' wounds were caused by other animals.
The Human Society is giving All About Animals a $2,500 Shelters in Crisis grant, according to a news release from the group.
Anyone with information about the break-in is asked to call Macon Regional Regional Crimestoppers at 877-68-CRIME.
