An Indianapolis mother was arrested Sunday on a preliminary charge of neglect of a dependent after her unsupervised son almost drowned in a Lawrence swimming pool. According to police, Vonda Goodman, 28, left her 5-year-old daughter and 9-year-old son at the pool at Hunt Club Apartments in the 5400 block of Calder Way on Sunday afternoon. No lifeguard was on duty. Police say the boy had to be rescued from the deep end of the pool by another swimmer. The boy, his sister and two other siblings were placed in foster care.
