When Linda Brown misses the first day of school after winter break, loved ones know something is wrong. Linda would never let her students down. Linda is a beloved special education teacher at Robert Healy Elementary School in the Bridgeport neighborhood of Chicago, happily married to Antwon Brown. Chicago PD is desperately searching for the missing school teacher. The special educator was last seen by her husband on Friday evening and by neighbors Saturday morning. Linda misses a weekly appointment that day, and isn’t answering her phone. Concern turns to fear when Linda hasn’t returned home on Sunday. Though Antwon last saw Linda Friday night, neighbors say they spotted her Saturday morning near their home. Linda’s purse, with her wallet and phone, is missing from the home, and her phone rings when called. Family members and friends retrace the teacher’s last known steps, but don’t find any leads.  Her sister’s husband, Lorenzo, tells “Crime Stories” staff that Linda’s vehicle has been located at 35th and Lake Park. Security footage also shows her walking across a pedestrian bridge alone on January 3, at around 3 a.m., according to the husband.  Linda is 5 feet tall, 130 pounds, with brown hair and eyes, last seen wearing a long, puffy black coat with shiny Ugg-style boots. Authorities are searching the area where her blue Honda Civic, plate number CX57470, was located on Wednesday afternoon. Anyone with information on Linda Brown should contact Chicago PD SVU detectives at 312-747-8380.
