They discovered that Leslie had been involved in most of the recent major bank robberies committed in the United States.

The bank was located on the first floor, and a barber shop ran by a man named Mr. Kohlman was in the basement.

[3] George Leonidas Leslie was an architect, art patron, socialite, and bank robber who moved to New York City in 1869.

The planning initially involved at least Leslie, Billy Porter, Gilbert Yost, Johnny Irving, John "Red" Leary, and Thomas "Shang" Draper.

He also located and bribed a vault maker, and learned how to duplicate the bank's safe's combination lock.

Draper and Leary cuffed his hands behind his back, gagged him, and wedged him between two of the vault doors, which Leslie tried to stop but failed.

[12] After laying low in Philadelphia, Leslie returned to New York and met with Draper and Leary in a saloon in Brooklyn.

[15] Leslie thought that the gang, police, or Pinkertons would come for him eventually, and started making plans to protect himself.

[15] Leslie's nerves led him to the plan to pull off the Institution robbery by himself, which would mean double-crossing the gang and Mandelbaum.

During this time, a police officer looked into the darkened lobby, and spotted Red Leary cleaning with a feather duster.

[19] Leslie convinced Yost and later, others, to hold off on the robbery until the spring, when there would be more money and securities locked in the vault.

In actuality, Leslie planned to use the time to rob the bank with another gang that Grady provided him, not with Draper, Irving, Leary, Porter, or Yost.

[15] In early April, Leslie contacted Grady, who gave him one of his top men as a bodyguard, Johnny Walsh.

Leslie told Molly he would retire from the revenue service (his story to avoid mentioning his criminal career), because he had made dangerous enemies.

[20] Leslie returned from Philadelphia in late May, and went about his business as normal at his Greene Avenue cottage, with Walsh by his side.

Evidence suggested that he was murdered at another location, and then transported to Tramp's Rock while hidden in a wagon's hay.

[3] In Werckle's account, he was putting on clothes, when the door to his sitting-room was noiselessly opened, and seven or eight men wearing masks walked in.

[3] A lithographer who worked on the third floor said he used the Bleecker Street entrance to go upstairs at or after 6 a.m., and found the door was open.

Officer Van Orden had a beat at that section of Bleecker Street from 6 to 8; he said that around 6:20, he looked inside the bank and saw nothing suspicious.

[3] The men entered the Bleecker Street entrance with the keys they received from Werckle, then locked it from the inside.

Kohlman could not hear the noise from below because the foundation of the vault room was of "enormous thickness" and made of cement.

The main safe door was wrenched off its hinges and laid on the books, as to deafen the sound of it hitting the floor.

They hurried their theft, and in the process, left the chisel inside, and the boxes and workman's kit on the ground.

[28] Werckle said that after a "long time" waiting in his apartment, there was a pounding from below, and then one or two of the robbery came back upstairs and inside.

After the men left, Werckle remained quiet for 10 to 20 minutes, then looked out his window facing the Bleecker Street entrance and saw nobody at the bank.

[3] Kohlman said he heard the vault clock strike 9, and then, twenty minutes later, Werckle came in with his hands still cuffed.

A consultation was held at the Fifteenth Precinct Police Station at 11 p.m. that night, and afterwards, the force's "best detectives" were sent to scour the city.

[27] Shevlin gave $600 back to Kelly, for the purposes of hiring a lawyer to go to Washington D.C. to prevent the passage of a Congressional bill which authorized the issuance of new United States bonds to replace those which were stolen.

[28] In June 1879, Glean, Jimmy Hope, Schoolin, Shevlin, and Kelly were arrested and charged with robbery.

[27] Investigators discovered that Leslie had been involved in most of the recent major bank robberies committed in the United States.
