Summary based on the NamUs case record (MP11470) and 12 other sources
On May 12, 2000, 1-year-old Sidney Keara Smith, her 1-month-old sister Monique, and their mother, Jennifer Lancaster, disappeared from Topeka, Kansas. The three were last seen leaving their home around 8:00 p.m. to visit an acquaintance, but they never arrived at their destination. Jennifer's 1994 Jeep Cherokee was found abandoned in an apartment complex parking lot, with all personal items, including baby car seats and keys, missing from the vehicle.

Sidney’s father was interviewed by police, but no substantial leads emerged, and the case remains unsolved. Despite thorough investigations, no evidence has surfaced about the family's whereabouts. Investigators have noted that Jennifer had been removing personal belongings from her residence prior to the disappearance, which adds an element of mystery to the case. Although there is no definitive evidence of foul play, it is considered unusual that Jennifer never contacted family or friends again. Sidney's case is still listed as an endangered missing person.

Authorities have periodically released age-progressed images of Sidney and her sister, but no significant breakthroughs have been made in the years since their disappearance.
