Police learned from a tip that Miller was living in the Barry Farms Public Housing Project. They say he was arrested there without incident.
Police also say they took evidence from Miller's home.
Goodman's body was found in the trunk of a rental car in Philadelphia. Police believe Goodman was killed in the home of an Edgemoor woman, one of two women found shot to death in Chester, Pa.
Police are still searching for Ronald James Collins, who is also wanted in Goodman's murder. A third suspect, Anthony Butler, was arrested in October.
