A Houston mother who drowned her two children, ages 5 and 7, and then hid their bodies under a neighbor’s house in 2016 pleaded guilty to two counts of murder on Monday in exchange for 40 years in prison, Harris County District Attorney Kim Ogg said.

Some of the Houston-area’s most notorious crimes will be the focus of major trials this year – including the senseless shooting death of 7-year-old Jazmine Barnes and the horrific drowning deaths of siblings Oralyn and Kayana Thomas, whose bodies were found in a crawlspace underneath their neighbor’s home.
