Wichita police say a couple has been arrested in the death of their 2-year-old son.

Police spokesman Officer Charley Davidson says the boy was found dead in a crib in a south Wichita home Thursday night.  A 4-month-old boy was hospitalized and will be placed into protective custody.

The Wichita Eagle reports 22-year-old Brandi Kai Marchant and 28-year-old Patrick Javonovich were booked into the Sedgwick County Jail on Friday.  Davidson said they are being held on suspicion of committing felony murder.

Davidson says police who responded to a call about a domestic disturbance found the couple walking back to the home.  He says it was not yet clear how long the children were left alone in the home.

An autopsy will determine the boy’s cause of death.
