Moscow, Jan 29 (IANS/RIA Novosti) A 32-year-old Russian has been arrested for the murder of 13 retired people more than seven years ago, the interior ministry said Tuesday.
Police suspect the man from Pskov region targeted the retirees in a killing spree.
The victims were poor, single pensioners over 70 years old, police said.
The man has confessed his role in the killings, but police do not yet have enough evidence to confirm his guilt in the crimes, said Igor Mezinov, a spokesman for the ministry's criminal investigation unit.
Police suspect the man, currently serving an eight-year sentence for robbery, committed the murders in Rostov and Pskov regions between September and December 2005.
The suspect "entered elderly people's homes, offering to buy an iron, a tea kettle, or something else", the ministry said.
"Upon entering the apartment, he quickly assessed the situation, after which he made the decision to kill the person."
