Documents prepared by slain detective show abuse of murdered 7-year-old boy

KANSAS CITY, Kan. -- (WDAF) -- Documents prepared by Kansas City, Kan., police detective Brad Lancaster, who was killed in the line of duty in May 2016 at the age of 39, show the cruelty a seven-year-old Kansas City, Kan., boy suffered before he was finally killed by his father and stepmother.

The remains of Adrian Jones were found in a pen where pigs were kept.

“Worst thing that I have ever had to see at this point in my career, and I hope to never see anything this bad again,” said Det. Mark Bundy with KCK Police Department.

Lancaster was a lead investigator in the case of Adrian Jones. Officers responded to a domestic disturbance at the Jones' home in November 2015. He said that injuries to Heather Jones were consistent with being beaten and choked. Lancaster wrote in the document that at that time, Heather told him that her husband's 7-year-old son AJ had died in the home on or about September 28th and that Michael disposed of his body on the property in an effort to conceal the death and the severe child abuse.

After obtaining a search warrant and finding AJ's remains, Detective Lancaster went back out to talk to Heather Jones. According to the document, she showed Detective Lancaster a Zap Enforcer flashlight that she said was used on AJ. During interviews with Lancaster, Heather Jones looked at pictures of AJ which Lancaster believed showed burns, open sores and scarring from the Zap Enforcer. Heather admitted that she and Michael Jones both used the device on AJ.

DNA samples were taken on the Zap Enforcer's electrode portion of the device. Detective Lancaster requested a warrant to obtain a saliva sample for DNA from Heather Jones to either confirm or eliminate her DNA on the electric shock device.

During discussions with Heather, Detective Lancaster also learned that Heather was an avid Facebook-user. Lancaster got legal access to a Facebook page in which Heather was a member. He noted finding a Facebook conversation Heather had with another member of the page in which she discussed not being able to handle AJ. She said he 'kills everything he comes in contact with and has to be restrained 95% of the time.' She also said 'Not even 8 minutes ago he flipped my 4-month old out her bassinet while I went pee.'

During the Facebook page conversation, Detective Lancaster recognized a reference Heather made to zombie television show, 'The Walking Dead', an episode titled 'The Grove', in which Carol decides she needs to kill a child named Lizzie because she has become too dangerous and killed another child.
