(CNN) -- Police arrested suspected serial strangler Antonio Rodriguez on Monday after DNA testing linked him to the sexual assault and murder of at least three women in a central Philadelphia neighborhood, according to Detective Justin Frank.
"We're hopeful that this will put an end to this," Frank said.
The announcement came just moments after a press conference in which Philadelphia Police Capt. James J. Clark announced a "major break" in the case, with forensic evidence putting Rodriguez at the scene of the three homicides.
Clark had said Rodriguez is a homeless man considered "extremely dangerous.
Rodriguez, 21, is suspected of killing Casey Mahoney, 27; Elaine Goldberg, 21; and Nicole Piacentini, 35, Clark said.
It is not clear how Rodriguez was located.
Last month, a 33-year-old woman was pulled into an alley and may have been the victim of the same attacker, police said.
Despite being choked, punched and hit on the head with a brick, she escaped her assailant, who fled from the scene, according to the police report. CNN
