 The career criminal seen dragging the dead body of his longtime girlfriend on a dolly on Staten Island strangled her to death before trying to hide the body, prosecutors said Sunday. Police identified 26-year-old Obiamaka Aduba as the victim on Saturday. Her husband, Anthony Lopez, 31, is the man police believe wheeled her lifeless body down a Mariners Harbor street a metal dolly on Friday after he allegedly strangled her to death. Sources said Anthony Lopez, 31, was picked up in East Harlem Saturday morning, thanks to a Crime Stoppers tip. Cops had been searching for Lopez since early Friday morning when an off-duty police officer observed him wheeling Aduba's lifeless body on a metal dolly in Mariners Harbor, police said. The city medical examiner still has to determine the cause of the woman's death. PRIOR ARRESTS 
 
 Lopez has a lengthy criminal history, including 34 prior arrests, 15 of which are sealed.
– Neighbors describe Anthony Lopez as a mentally disturbed crack addict, which would go some way toward explaining his alleged crime. Police say the 31-year-old strangled his wife to death and pushed her body on a metal dolly down a street in Staten Island Friday morning, reports the New York Daily News. He allegedly dumped the body of Obiamaka Aduba, 26, on the front lawn of a home and took off after an off-duty cop spotted the corpse, which had been partially covered by a sheet, the Staten Island Advance reports. Lopez was arrested in East Harlem on Saturday after officers acting on a tip chased him down. Authorities say Lopez has 52 arrests and a long history of domestic violence involving Aduba, reports the New York Daily News. "It was due to drugs. He's been crazy, he's mentally disturbed," a neighbor tells PIX11. In a court appearance Sunday, Lopez pleaded not guilty to second-degree murder and begged for methadone to help him with drug withdrawal. He's being held without bail and will appear in court again on Tuesday. In Sunday's court appearance, Lopez was also charged with criminal mischief for throwing a brick at a car windshield earlier this month.
