Investigators have detained a police cadet over the shocking killing of the wife and child of a drug control officer in St. Petersburg over the weekend.
Investigators classified the killing, which was allegedly committed by Ilya Komarov, 20, a cadet in a college run by the Interior Ministry, as murder, the Investigation Committee's official spokesman Vladimir Markin told RIA Novosti on Monday.
Murder charges carry a maximum sentence of 15 years in jail.
Komarov told investigators that on Saturday he killed the wife, 12-year-old son and dog of the unidentified Federal Drug Control Service officer after quarreling with the wife, who was his neighbor.
He stabbed the wife woman, child and dog with a knife, investigators said, adding that the drug control officer found the three dead bodies after returning home from working a weekend shift.
Investigators said Komarov's girlfriend, who was living in the same apartment building, had also argued with the drug control officer's wife in past.
"We're not ruling out that charges could be pressed against her [Komarov's wife] as a co-conspirator," Markin said.
