New suspect identified in Annie McCarrick cold case murder investigation.

Irish police have identified a suspect in the murder investigation of American student Annie McCarrick, who went missing in Dublin in 1993. The suspect lived in the same neighborhood as McCarrick, and authorities are building a case against him. The case was upgraded to a murder investigation last month after a new lead was received. Investigators are searching for a purse McCarrick was seen carrying in CCTV footage shortly before her disappearance, which was never found.
