The bodies of two adults were found inside an Alton apartment on Thursday. 25-year-old Michael A. Smith of Carrolton and 32-year-old Sara E. Engles of Alton, were discovered by a maintenance worker at the residence in the 1500 block of Sparks late in the morning.   Their cause of death remains under investigation by the Madison County Coroner, but there were no signs of violence at the scene. 

Engles did have a 2-year-old child who was not there at the time the bodies were discovered.   The home contains two other apartments, and police continue to investigate the incident although they are working on the possibility the two died from a drug overdose, as drug paraphanalia was found at the scene.
