A 22-year-old woman visiting friends in the college town of Columbia, South Carolina, was murdered by a “completely random” stranger on a multiday crime rampage, which saw the suspect “wreaking havoc across two counties and six or seven police jurisdictions,” according to local officials.

Alexander Dickey, 30, is accused of killing Logan Federico at a rental property where she was staying with friends, according to the Columbia Police Department and Lexington County Sheriff’s Office, which held a joint press conference Monday announcing Dickey’s arrest and what allegedly happened.

Columbia Police Chief William Holbrook told local CBS affiliate WLTX and other outlets that Dickey was breaking into two homes early Saturday morning in the 2700 block of Cypress Street when he crossed paths with Federico. The residences are side by side, and Dickey was allegedly stealing items such as wallets and credit cards from both of them. Federico had returned to the home where she was staying with several of her friends at around 3 a.m., according to Holbrook.

“While in this residence, we believe that he [Dickey] enters a room where Miss Logan is located and fires a fatal shot,” the chief said.

Officers in Columbia, which is home to the University of South Carolina, responded to the home at around 11:14 a.m. Saturday after Federico’s body was found inside by her friends. Dickey is accused of stealing a car from the residence and taking it to commit more crimes.

“The suspect drives away in the stolen vehicle and heads towards West Columbia and goes on what can best be described as a shopping spree,” Holbrook said. “He uses stolen credit and debit cards, to go to multiple stores in Lexington County. He ultimately drives to Saluda County and attempts to make additional fraudulent purchases.”
