Pubdate: Mon, 12 Oct 1998 Source: Philadelphia Inquirer (PA) Contact: http://www.phillynews.com/ Author: Anne Barnard UNKNOWN DRUG IS BLAMED IN 2 DEATHS Police yesterday were trying to trace the source of a heroinlike drug that killed two Roxborough men over the weekend, investigators said. Joseph Brown, 41, of the 300 block of Dupont Street, and Joseph Alvin, 48, of the 6000 block of Ridge Avenue, were found Saturday afternoon, each in his own home, Detective Sgt. Winton Singletary said. The men died after taking a drug they believed was heroin, Singletary said. The powdery substance came in packets decorated with a picture of a clock, its face stamped with the words "Full Time." "We don't know if it's heroin," Singletary said. Police are trying to identify the substance through toxicology tests, which could take weeks. No one else had died or fallen ill from the drug, police said yesterday. Police believe drugs also may have contributed to the death of a man who crashed his sport utility vehicle in the area hours before the men were found dead Saturday. The driver, Mark Heller, 44, of the 300 block of South 24th Street, overturned his Mitsubishi Montero at Lyceum and Manayunk Avenues. He was pronounced dead at the scene. A plastic bag of a powdery substance that could have been heroin or cocaine was found in the vehicle, police said. Toxicology tests were being performed. There was no indication that Heller used the "Full Time" drug, investigators said. Police were not sure how many other people, if any, had purchased it. "We're trying to ascertain where they bought it," Singletary said. "It appears they got it from the same individual." He said one of the men "came into some money, and I guess he bought this for him and his buddy." Brown's sister-in-law, Sharon Crompton, said Brown had recently inherited some money from his late mother. He was to have started a new job today, she said. "He was a good guy," said Crompton, who answered the telephone yesterday at Brown's house, where relatives had gathered. "A hard worker. He wouldn't hurt anyone." Brown and Alvin were found after a friend or family member called the Fifth Police District about 2 p.m. Saturday, Singletary said. He said it was unclear when they took the drug. In the earlier fatal accident, Heller hit several objects and resumed driving several times before the final crash. A preliminary report filed by the Accident Investigation Division gave this account: Heller was driving west on Lyceum Avenue shortly before 4 a.m. when he lost control of the vehicle at the intersection with Manayunk Avenue. He crossed the street and hit some concrete steps, backed up, and hit a car traveling behind him. Then he struck a pole, a parked vehicle and another pole. The vehicle flipped, landing on the driver's side. - --- Checked-by: Patrick Henry
