Medical Conditions Jackson was taking medication for depression and a sleeping disorder, but his medicine was left behind when he vanished. In addition, he was reportedly using crystal methamphetamine and other club drugs around the time of his disappearance.
Distinguishing Characteristics Caucasian male. Light brown hair, blue eyes. Jackson has scars on his nose and between his eyes. He wears a pair of small eyeglasses. He has a receding hairline.
Details of Disappearance Jackson was last seen on June 27, 2004 at his apartment in Drake Towers in the vicinity of the 1800 block of north Andrews Avenue in Fort Lauderdale, Florida. He had a friend from North Carolina, John Bass, visit him that day. They went dancing at the Coliseum dance club in Hollywood, Florida, then arrived at his apartment at 4:15 a.m. Security cameras showed them entering the building.
Bass says he went to sleep at 5:00 a.m. and when he woke up at 11:00 a.m., the lights and television were on but Jackson was gone. He left a note behind but the contents have not been released. He has never been heard from again.
Most of Jackson's personal belongings, including his house keys, the access card to his apartment building, his car, his medicine, and his cellular phone, were left behind. His wallet, passport, and credit cards were missing, however. The surveillance cameras in the apartment building malfunctioned about an hour after Jackson arrived home with Bass and did not record him leaving the building.
Jackson's loved ones say it would be uncharacteristic of him to leave home without his cellular phone. There have been no charges to his credit cards or withdrawals from his bank account since his disappearance, but someone checked his email and listened to his cellular phone voice mail messages at 8:40 a.m., almost four hours after he was last seen.
Bass has not been publicly named as a suspect in Jackson's case. The two men had dated occasionally and Jackson wanted a long-term relationship with him, but Bass did not want one. Fourteen vials containing residue of gamma hydroxy butyrate (GHB) and crystal methamphetamine were found in Jackson's apartment after his disappearance, but it is unclear whether drugs played a role in his case.
There are some similarities between the Jackson and Rhodes/Block disappearances. All three men are gay, all of them left behind most of their belongings, they all disappeared in late June, and all of them were reportedly involved with drugs. (Jackson reportedly used crystal methamphetamine and other club drugs, and Block and Rhodes may have handled drug money for one of Rhodes's acquaintances.) However, police say the similarities may be merely coincidental; they cannot find any conclusive evidence to link Jackson to Rhodes and Block's disappearances seventeen years earlier.
All of the men are gay, all were roughly within the same age group, and they all disappeared from the same area. Rhodes and Block disappeared first, in 1988. Shumaker disappeared from Tampa in 1995. Thompson disappeared in 2001 from Clearwater, Florida, and his truck was later found abandoned in Tampa. Thompson, like Williams, disappeared from Tampa. Galehouse and Wachholtz disappeared from Tampa within a day of each other in December 2003. Wachholtz's body was found in mid-January 2004, but the other men remain missing.
In September 2012, Schweickert was charged with two counts of first-degree murder in the deaths of Wachholtz and Galehouse. In June 2016, he pleaded guilty to both murders and was sentenced to life in prison. This is on top of the 40 years he is already serving for the GHB-related charges. He admitted he and Lorenzo conspired to meet single gay men and turn them into "sex slaves", then either kill them or sell them once they became tired of them.
Schweickert spoke about Galehouse and Wachholtz's murders in detail and he has agreed to testify against Lorenzo in court, but Lorenzo has not yet been charged in any deaths.
Jackson is described as a driven, goal-oriented person. He has an engineering degree and a master's degree in business administraton (MBA). He enjoys running, working out at the gym, and dancing in clubs. He recently purchased a new silver BMW and invested in real estate prior to his disappearance. Jackson's case remains unsolved. Investigators have stated that other than their lifestyles, there's no hard evidence to tie him and the other missing men to Lorenzo.
