I woke this morning at exactly 9:40, the time 35 years ago that Juan Lucero Escalante took your life. I wish I could speak to you to tell you I learned from Sheriff Estrada in Santa Clara County (Nogales) that they have issued an arrest warrant against him for a cold case homicide done just before his path crossed yours. I can’t believe that much time has passed and I still miss you every day. (“You are always on my mind…”)
