Langford was in court on Tuesday, pleading not guilty for at least 15 home invasion robberies on the westside.
The suspect is accused of targeting elderly women.
Police call him the Westside robber. He preyed on victims at night, and in one case, he tied up a 90-year-old for hours and stole money and jewelry from her.
"He was someone who was after very vulnerable people, and whether or not he used a weapon, he could have caused a heart attack, he could have caused horrible things to happen to these old ladies in the middle of the night," said L.A. City Councilman Jack Weiss.
Tips led police to Langford, and then they watched him until they had enough evidence to make an arrest last Friday.
"This was clearly a bad guy who was patient and who studied his surroundings. So, LAPD got patient, and they studied him and his surroundings," Weiss said.
"We have some recovered items of stolen property from a number of victims. We also have forensic testing in terms of footprint impressions that's made linkages," said Captain Denis Cremins, Los Angeles Police Department.
The District Attorney's office is filing 10 charges against Langford for robberies committed over the past 2 1/2 months.
In one case, Langford is accused of forcing a 96-year-old woman into her home and ransacking the place
This is a third strike for Langford. He was convicted of assault with a deadly weapon and burglary in 1982. So, if convicted in this case, Langford could face life in prison.
Langford is due back in court on September 22.
