Alonso told investigators he and Fields were having an intimate moment along the lakefront, a confrontation ensued, and he choked Fields. He claimed he believed Fields was alive as he walked away because she was yelling at him.

Alonso made his first court appearance Wednesday and his bail was set at $1 million. It wasn’t clear whether he had an attorney who might comment on his behalf.
