Ren Weddles was 1 year old when he and his twin sister, Setina Weddles, disappeared from Stockton, California, on January 4, 2018. The family — including the twins’ parents and other siblings — was reported missing at about the same time.

Five days later the parents and three siblings were located in Stockton, but Ren and Setina were not with them. Extensive searches have been conducted and authorities have said they suspect foul play, yet the twins’ whereabouts remain unknown and details are sparse.

If anyone in Stockton or the surrounding area remembers seeing Ren or Setina in early January 2018, or has information about the family’s movements then, please come forward.
