Ryan LeVin, 34, who had been on probation following a 2006 high-speed car chase in Chicago, must also attend a special drug treatment program in the Cook County Jail, Circuit Judge William O'Brien ordered.
LeVin, who is from Hoffman Estates, Ill., and had recently received permission from a judge to stay at his parents' Fort Lauderdale oceanfront condos, will now remain in jail until at least his next court appearance April 9.
Wearing olive-green prison garb and designer eyeglasses, LeVin showed no reaction to Thursday's decision. He did not speak during the brief hearing at the Skokie courthouse.
Fort Lauderdale police have not named LeVin or anyone else as a suspect in the Feb. 13 accident that killed British businessmen Craig Elford, 39, and Kenneth Watkinson, 48, as they strolled along State Road A1A to their beachfront hotel.
The victims' families are expecting the bodies, kept previously at the Broward County Medical Examiner's Office and then a funeral home, to arrive by air in Britain today , said Annette Hugues, a British consulate spokeswoman in Miami.
At least one witness called 911 shortly before the two men were fatally hit from behind to report that a Porsche and another light-colored sports car were racing.
The Porsche, which belonged to LeVin, was found abandoned soon afterward and impounded by police.
LeVin had told the Sun Sentinel he was not behind the wheel at the time of the crash.
An offspring of a wealthy Chicago-area family, LeVin had agreed to attend drug counseling as part of a plea deal for a July 2006 chase that injured one Chicago police officer and two motorists.
On Monday, he was ordered held at the Cook County Jail without bond for violating his terms of probation. Thursday's hearing was to see whether he met eligibility requirements for the jail's drug treatment program.
