Summary based on the NamUs case record (MP38053) and 5 other sources
On a cold winter day in Lansing, Michigan, 34-year-old Matthew Adam Etheridge, who often went by his middle name, Adam, was last seen on February 23, 2017. He was in the 700 block of Pruden Street when he vanished, leaving his loved ones with unanswered questions. The last person to have seen him was the mother of his child. A day before his disappearance, on February 22, 2017, he had made a purchase in Grand Rapids, Michigan, a detail that adds another layer to the mystery of his last known movements. At the time he went missing, he was wearing a hooded sweatshirt, pants, and white Adidas tennis shoes.

Matthew is described as a white male with brown hair and brown eyes, standing at 5'10' and weighing around 200 pounds. His appearance is distinguished by several tattoos, including an alligator on his upper left chest, a mermaid on a surfboard with a shark on his left arm, and a skull and crossbones on his left shin. He also has a large and intricate tattoo on his back featuring a skull with clouds and symbols representing 'I love Dad'. Additional tattoos include the words 'Never be the same' on his stomach and 'Dirty South' on his chest. It is also noted that he suffers from post-traumatic stress disorder and other mental health challenges.

The investigation into Matthew's disappearance has been ongoing, with the Lansing Police Department handling the case. Despite the passage of time, few details about what may have happened to him have been made public. His case is classified as an endangered missing person, and he remains listed as a long-term missing person by the Lansing Police Department. The circumstances surrounding his disappearance remain unclear, leaving a void in the lives of those who know and love him. The lack of answers has been a heavy burden for his family, who continue to hope for his safe return. An overview of the case highlights a man who seemingly vanished without a trace, with his last known activities being a simple purchase and a final sighting by his child's mother. The reasons behind his disappearance are unknown, and with limited information available, the path to finding him has been fraught with difficulty.
