TROY, Mo. – Two grandparents from Troy, Missouri, are dead, and police say their grandson is to blame.

The Troy Police Department launched the homicide investigation Tuesday night, after a couple was found dead inside a mobile home near the intersection of Eames and East Cherry streets.

According to a spokesperson for the Troy Police Department, family members contacted police to request a wellness check. Officers arrived at the home around 7:30 p.m. and discovered the couple dead.

Law enforcement identified the man and woman as Donald and Kathy McRoberts. Donald was 71 and Kathy was 58. Investigators have not disclosed how they died, but suspect they may have been dead inside the residence since earlier in the week.

Family members said they were pillars in the community and loved by all.

“I still can’t believe it. I realized that my uncle and his wife were involved in a double homicide. I dropped my phone when I found out,” Nathaniel Jones said.

Some residents told investigators they heard gunshots on Tuesday or the day prior. Neighbors are still in shock.

“It’s scary to think that something that close could happen,” Jonathon Haas said.

Police tracked down the individual after a short manhunt. FOX 2 is no longer identifying the person of interest, since he has yet to be charged with a crime.

“The most important thing is he’s safe, the community safe. It’s a tragedy what happened to the victims, but he’s off the streets,” Troy Police Chief Jeff Taylor said.

The matter has been turned over to the Lincoln County Prosecuting Attorney’s Office for possible charges.

The investigation is still ongoing. Anyone with information on the case is asked to contact the Troy Police Department at 636-462-7632 or the Lincoln County Sheriff’s Department at 636-528-6100.

Troy is located approximately 55 miles northwest of St. Louis.
