Conchita, who was trained by James Glenn Jr. and whose jockey was Henry Lopez, is the 10th horse to die from a racing or training injury at the Cypress track this year, according to the California Horse Racing Board.

Los Alamitos was placed on probation last summer after a number of racehorses died at the track. At least 20 died in 2020 from racing or training injuries, while another 10 were found to have died from gastrointestinal or other illnesses.

This is the second instance of racehorse deaths that has made the news in the last two days, as Santa Clarita Park reported its 20th horse death of the year on Sunday.
