OLATHE, Kan. (AP) — Authorities responding to a report of a foul odor found malnourished 3-week-old twins under a bed in an apartment containing their mother's decomposing remains.

Both infants were taken to a hospital Friday, where one, a girl, later died. Her twin brother was in critical condition Saturday. Authorities said their 36-year-old mother, Virginia Wanjiru Njoroge, appeared to have been dead for several days.

An autopsy found no evidence that foul play contributed to her death, police said.

Emergency crews who found the woman noticed car seats and other baby items in the apartment, leading to a more thorough search.
