ROCKVILLE, Md. (WUSA9) -- Police continued their round-the-clock investigation into the Mother's Day murders of two Montgomery County grandparents Tuesday. Neighbors have grown increasingly uneasy about the unsolved, unexplained violence in their tranquil, exurban neighborhood.
A Montgomery County Police Department spokesman labeled the crime a burglary, but said it remained unclear what, if anything, was taken from the home of victims Dick and Jody Vilardo.
A source close to the investigation told WUSA9 that detectives found a large, messy crime scene indicative of a violent struggle, which made it difficult to tell what might be missing.
Outside the Vilardos' modest home in a wealthy neighborhood, detectives could be seen walking through the woods, looking for evidence until sundown. At 9 p.m., evidence collection vans arrived and investigators searched the backyard by flashlight for more than an hour.
