Not saying that is what it is, just trying to make educated guesses, but to me it makes the most sense.
A lot of little signs I could point to but a lot of that is read between the lines stuff in terms of actual facts the biggest thing that got me thinking it was neglect was the response time frame Kansas child protective services has for child abuse/neglect cases to be investigated. They have a same day, 72 hour, 20 day time frame with the 72 hour and 20 day time frames not counting weekends or holidays. The Kansas Protection Report Center specialist determines the response time and same day is when they believe the child is in imminent danger. If they don't believe the child is in imminent danger they have 72 hours to investigate all other child abuse cases. The 20 working day timeframe is reserved for reports relating to neglect, for reasons not related to maltreatment.
I don't know the exact date the report was opened but I'm going with either date of latest police report, which was March 14th, or the following Monday which was March 17th. It was reported by a Kansas TV station his child was removed from the home on April 5th, which depending on day they got the initial report would have meant they concluded their investigation in 15 or 17 working days and thus far surpassing the 72 hour timeframe to investigate for abuse but wrap up the neglect investigation with a few days to spare.
