"He stared into my eyes the entire time as I told him over and over how much I loved him and promised him I would be okay," the actor continued. "After a couple of minutes, his body seized a few times, and he drew his last breath."I’ve experienced a lot of loss in my life," Anchondo revealed, "but nothing could prepare me for this.
