Los Angeles (CNN) A task force that looked into scores of horse deaths at California's Santa Anita Park found no animal cruelty or criminal activity, Los Angeles County District Attorney Jackie Lacey said Thursday.

The number of horses that were being euthanized or dying after accidents at the famed facility gained nationwide attention when officials briefly suspended racing in early March over concerns about the number of deaths.

"Horse racing has inherent risks but is a legally sanctioned sport in California," Lacey, who led the panel of prosecutors and investigators, said. "Greater precautions are needed to enhance safety and protect both horses and their riders."

The task force looked into the 56 deaths that occurred between July 1, 2018, and November 30, 2019, and "did not find evidence of criminal animal cruelty or unlawful conduct relating to the equine fatalities."

The task force, formed in March, had recommendations for post-death investigations, identifying preexisting conditions, track maintenance and enforcement. It proposed an annual fatality report, facility investigations, enhanced penalties for violations, and establishment of a tip line to encourage reporting of suspected animal abuse.
