There were a few bits of tantalizing chatter that the FBI managed to record in spite of the obliterating wall of rock and disco music, such as Sepe telling an unidentified man about "... a brown case and a bag from Lufthansa ..." or his telling his girl friend, Hope Barren, "... I want to see ... look where the money's at... dig a hole in the cellar [inaudible] rear lawn ..." But this was still not enough to connect Sepe and his pals to the theft.
After a while the crew became so adept at slipping tails that sometimes one or more members of the gang would disappear for days at a time. McDonald received reports that his suspects had been spotted as far away as Fort Lauderdale and Miami Beach. Of course, he could have revoked their paroles and sent Jimmy, DeSimone, and Sepe right back to jail for consorting with each other, but that was not going to solve the Lufthansa robbery, nor was it going to get any of the money back.
McDonald knew from the start that Lufthansa had been an inside job. How else would the six gunmen have known which of the twenty-two giant cargo warehouses in the 348-acre Kennedy freight-terminal area just happened to have six million dollars in cash and jewels sitting around over the weekend? Such large sums are usually picked up by armored truck shortly after they arrive and are Immediately deposited in banks. The gunmen also knew the names and the locations of all the employees working that night; they knew about the perimeter alarms that required a special magnetic key, and they knew where to find the key and how to disconnect the automatic security cameras without sounding the silent alarm. McDonald was convinced that if the surveillance and electronic techniques failed to catch the pros, the amateur inside man would eventually lead to Burke and the men who actually carried out the robbery.
Lufthansa's own security men gave McDonald Lou Werner's name within hours of the robbery. Werner had already been the suspect in an earlier theft of twenty-two thousand dollars in foreign currency, but there had not been enough evidence at the time to arrest him or have him fired. This occasion was different. It turned out that Lou Werner had prevented the Brink's armored-truck guards from making their routine pickup of the six million in cash and jewels on the Friday before the robbery. Werner had claimed that he had to get the approval of a cargo executive to sign the release. One of the Brink's guards had complained that this was not the procedure, but nevertheless, Werner had disappeared for the next hour and a half and had not reappeared in the cargo area until after the guards had been ordered to continue their rounds without the Lufthansa money. So Lou Werner was not only responsible for the money and jewels being left at the airport over the weekend but he was one of the few Lufthansa employees who knew it was still there.
Such pros as Jimmy Burke never seemed to talk about anything indictable, even in what they had to assume was the privacy and safety of their own cars, but an amateur such as Lou Werner couldn't shut up. He seemed compelled to drop hints about the robbery to everyone he knew. He boasted about coming into some money. He told his barroom pals that he had paid off his bookies and loan sharks. He announced that he was heading for Miami to spend Christmas week.
To the agents involved, following up on Werner's domestic intricacies was more like plodding through a comic soap opera than investigating a robbery. They found, for instance, that just before the robbery Werner had told his estranged wife, Beverly, that he would be coming into a great score and that she would most assuredly regret having left him after twenty-three years. He told his best friend, William Fischetti, about the robbery at least a month before it took place and agreed to invest thirty-thousand dollars of the loot in Fischetti's taxicab business. Then, two weeks later, Werner found out that Fischetti, who was married, was having an affair with his estranged wife Beverly; he got so angry he called his old pal and withdrew from the business proposition. On the morning of the robbery, with the radio and newspapers announcing the spectacular heist, Werner was apparently still so incensed at his ex-pal that he called Fischetti at home and shouted, "See, big mouth!" and hung up. A couple of days after the robbery, when the newspapers were filled with headlines about the multimillion-dollar score, Werner proudly boast all to his girl friend, Janet Barbieri, a thirty-six-year-old divorced mother of three. Barbieri promptly burst into tears and screamed hysterically that he would wind up in jail. Werner was so depressed by his girl friend's reaction that he went to his local bar and proceeded to tell the whole story to his favorite bartender— but only after swearing him to secrecy.
The FBI, of course, talked to everyone who knew Werner, and just about everyone who knew Werner talked to the FBI. Fischetti, for instance, was so worried that his wife would find out about his affair with Beverly Werner that he agreed to cooperate fully as long as he wasn't interviewed in his own home. For weeks FBI agents met Fischetti in coffee shops and taxicabs, and he told them everything he knew— which was a lot.
Fischetti had known Werner for years and said that Werner and another Lufthansa cargo worker, Peter Gruenewald, had concocted the plan to rob the airline months before the robbery. Fischetti said the pair had hit upon the scheme after being involved in the theft of twenty-two thousand dollars in foreign currency and deciding that it was foolish to chance getting caught or fired for stealing such a paltry sum. If they were going to take any money from the vault and run the risk of getting caught, it might as well be for at least a million dollars.
Fischetti said that Werner and Gruenewald then worked for months on their heist, and when their step-by-step blueprint was finished, Gruenewald had the job of shopping it around the airport bars looking for the right men to carry it out. Gruenewald spent months testing one prospective holdup man, a notorious barroom rowdy, but decided against using him when he realized the man wasn't serious enough. When Gruenewald turned out to be much too slow in finding the robbers, Fischetti said, Werner took matters into his own hands and asked his bookmaker, Frank Menna, if he knew of anyone who could carry out the undertaking.
When the FBI first approached Gruenewald he denied any knowledge of the plan, but agents soon lined up the barroom rowdy Gruenewald had approached for the robbery, as well as Fischetti, as a witness against him. On Friday, February 16, nine weeks after the robbery, agents found that Gruenewald had applied for a standby ticket from New York to Bogota, Colombia, and then on to Taiwan and Japan. Gruenewald said he was on his way to see his estranged wife in Taiwan, where she lived with her family. Gruenewald was arrested and held as a material witness in the Lufthansa case. He decided to cooperate with McDonald in assembling the case against Werner.
McDonald knew that with the testimony of Gruenewald, Fischetti, Beverly Werner, Janet Barbieri, and Frank Menna he had enough evidence to charge Lou Werner as a participant in the Lufthansa robbery. McDonald had also compiled enough evidence against Angelo Sepe to charge him with the robbery and, more important, to get a warrant to search Sepe's girl friend's Mattituck, Long Island, house and yard for the money. The agents who had been following Sepe for weeks and had been listening to hours of rock music and snippets of conversation were convinced that the money was buried somewhere at Hope Barren's house.
McDonald's objective was not just to convict Werner but to convince him to cooperate with the feds. Werner had to roll over on the men he hired to do the robbery. But the day Werner was arrested he proved to be tougher than McDonald or any of the agents had thought. He had talked incessantly before his arrest, but he stopped talking once he was in custody. On the night of his arrest, after hours of questioning, Werner continued to insist that he had had nothing whatsoever to do with the robbery. He claimed he had boasted and lied about his role in the heist only because it boosted his ego.
