Agent Burger

Agent Burger was a federal investigator working with T. B. White on the murder investigation. His reports helped turn scattered witness accounts into a challenge to Bryan Burkhart’s alibi, while his warnings about informant exposure and private investigators’ interference revealed how vulnerable the inquiry had become. In the case of Pike, the search for a concealed lead became another contest over who controlled information—and who might be paid to keep it hidden.

Alibi and the Third Man

Witnesses placed Bryan driving with Anna Brown after the time he had sworn he left her safely at home in Fairfax. Agent Burger’s report identified the discrepancy as perjury before the coroner’s inquest, making it the first proven crack in Bryan’s account. The sighting did not establish what happened to Anna, but it meant investigators could no longer treat Bryan’s sworn timeline as reliable. The later accounts were less conclusive. Witnesses said Bryan and Anna had been seen with a third man, distinct from Bryan’s uncle, and Agent Burger recorded that this unidentified companion was reportedly with them. The last reported sighting together came at about three in the morning, when a Fairfax witness heard a man she believed was Bryan call for Anna to get into a car. After that, Anna disappeared from the trail. Agent Burger’s record preserved the unresolved presence of the third man as a central question rather than a settled identification.

Protecting Morrison

The investigation faced leaks and deliberate interference as well as unreliable testimony. Two private detectives, one associated with the William J. Burns International Detective Agency, exposed the Bureau’s principal informant, Kelsie Morrison, to local officials and had him detained on what investigators considered a fabricated robbery charge. Agent Burger condemned one detective’s conduct as damaging to the inquiry and suspected that obstruction was the detectives’ purpose, possibly at someone else’s expense. Morrison emerged from jail frightened. In a meeting with agents, he urged them to catch the killers before the killers caught him; Agent Burger warned him to watch for betrayal and traps. The episode gives Burger a practical role beyond gathering evidence: he recognized that an informant could be endangered by the investigation’s own compromised surroundings, and that protecting a source was inseparable from pursuing the case.

Pursuit of Pike

Pike presented a different kind of obstruction. He had been hired by William K. Hale in 1921 to investigate the murders, but had made no progress, according to what agents knew. An intermediary later told Agent Burger that Pike had nevertheless learned the identity of the third man seen with Bryan and Anna, and that Pike would disclose it only for an enormous payment. Burger regarded the arrangement as evidence of crooked dealing and pressed Pike, through the intermediary, to come forward. Pike did not comply. After his Kansas City address became known to investigators, he changed it, and Agent Burger wrote that agents believed he had been paid to disappear. They sought to locate and apprehend him. Pike was later caught in Tulsa, allegedly committing highway robbery, and offered the name of a local gambler. Investigators confirmed that the gambler had been drinking with Bryan and Anna at a speakeasy on the night of May 21, but established that he had gone home too early to be the third man. The lead failed, yet the pressure on Pike continued; he gradually disclosed that he had not truly been hired to solve Anna’s murder, but had been asked to conceal Bryan’s whereabouts that night.

Investigative Significance

Burger’s part in the inquiry is visible chiefly through reports, assessments, and warnings. He marked the conflict between Bryan’s sworn account and witness sightings, recorded the uncertain third-man clue, and treated attacks on Morrison and Pike’s apparent withholding as threats to the investigation itself. Together, these episodes show the case advancing not through a single decisive revelation but through the careful separation of usable evidence from testimony, leaks, false leads, and information offered for a price.
