Antonio Rodriguez, the suspect in the murders of three women in Kensington, has confessed to the murders, police sources said today.

Rodriguez, 22, gave a statement to police but has not been charged in the killings. Police arrested him Monday on outstanding bench warrants, hours after a DNA match in a database identified Rodriguez as the alleged strangler.

DNA evidence has linked Rodriguez to the deaths of three women since November. Investigators have taken another DNA sample from Rodriguez, which they expect will determine conclusively that he is the person police have been searching for.

Rodriguez, a convicted felon, was required to submit his DNA when he was released from jail this summer. That sample was not processed until December, due to a backlog of cases, and the testing was also interrupted by an upgrade to the database. The sample was uploaded into the system last week, and a match came back on Monday.
