Grigoriy Bukhantsov, Relative Of Slain Family, Arrested In Rancho Cordova Triple Murder (VIDEO)

A relative of the family slain in a brutal, triple murder in Rancho Cordova, Calif. on Tuesday has been arrested. Police say he is the only suspect in the case.

Grigoriy Bukhantsov, a 19-year-old man, is the brother-in-law of the mother and uncle of the two young children who were found dead in their suburban Sacramento home earlier this week.

The scene of the crime was reportedly so violent that chaplains had to be called in to counsel sheriff's deputies that responded, as well as neighbors and relatives.

Police say Bukhantsov allegedly stole the family's minivan and drove to a Denny's restaurant in Rocklin, Calif., KCRA reports. Employees at the restaurant told CBS Sacramento that Bukhantsov was so "agitated and rude" that they thought he would "dine and dash."

But after ordering a large plate of food, Bukhantsov fell asleep in his seat. Employees took the license plate number of the minivan, but had no idea that the man was a suspect in a triple murder.

An officer on patrol spotted the van around 2 a.m. Wednesday, according to KXTV. Judy Kregness, a Denny's employee, told CBS News that about 30 patrol cars soon arrived at the scene. A SWAT team detained Bukhantsov at the restaurant. He is being held without bail at Sacramento County Jail.

According to the Associated Press, Bukhantsov was on probation after spending seven months in jail for felony burglary, and he was allegedly drifting between homes of relatives. Neighbors of the family told AP there were "signs of trouble" the day before the slayings.

"There have been suggestions that something bad was brewing for some time," Sacramento County sheriff's spokesman Sgt. John Ramos said. He added that it appears Bukhantsov had a poor relationship with several family members.

A woman who identified herself as the slain mother's sister told KCRA that the family had received threats, but she didn't elaborate on the matter.

While police did not comment on the murder weapon, pending a coroner's report, Ramos told the AP that the violent encounter involved stabbing, slashing or slicing.

The victims have been identified as 23-year-old Alina Bukhantsov, who worked as a Sunday school teacher at a local Slavic church; her 3-year-old daughter, Emmanuela, and her 2-year-old son, Avenir.

A crying 6-month-old baby boy was also located unharmed in a crib.
