Officials say the reward for information relating to the shooting of several wild horses living along the Salt River is now $25,000.
A release from the Salt River Wild Horse Management Group (SRWHMG) says a matching donation from Animal Recovery Missions Investigations of Florida, has more than doubled what was previously a $12,500 reward.
The Maricopa County Sheriff's Office is investigating after one horse was killed and two others were injured in a shooting on October 21.
As of Monday, SRWHMG officials said no tips leading to the suspect's apprehension had been received.
MCSO says a witness saw a man wearing black shorts and a dark green shirt shooting horses along the Salt River near the Pebble Beach Recreation Area.
Anyone with information is asked to call the Maricopa County Sheriff's Office at 602-876-1011.
