Suspect arrested in killing of a former Russian submarine captain who reportedly attacked Ukraine

A 64-year-old man has been arrested in southern Russia for the shooting death of a former submarine commander who is alleged by some in Ukraine to have killed more than 20 civilians in a long-range missile strike last year.

Sergei Denisenko was detained on suspicion of shooting former 2nd Capt. Stanislav Rzhitsky, reportedly during a morning jog in the city of Krasnodar on July 10.

Denisenko was found in possession of a pistol and silencer, officials said. Some Russian media outlets identified him as a native of Sumy, a city in Ukraine.

Rzhitsky, 42, was attacked near the city’s Olimp sports complex where he often followed the same 4-mile path, according to the Russian online news outlet Baza, which didn’t specify the source of its report.
