Don't call a handful of Grimes County cases cold. Authorities are still hot on the trail for some wanted criminals.
"You don't want to close out a case until you've exhausted all efforts," said Grimes County Sheriff Don Sowell, "and all efforts have not been exhausted on these cases."
"Being a county as rural as Grimes County is, a lot of the old cases just don't go away in memory," said Sergeant Greg Eakens with Grimes County's sheriff's office.
Cases like the deaths of two girls who were hit by a car while walking down FM 1774. The young ladies were together near the small community of Todd Mission on July 13, 1991. Authorities say this incident may be a hit-and-run.
Cases like a homicide at the First Materials building in Navasota. On August 29, 2000, Arnold Peterson was killed at the Business Highway 6 work zone. Authorities believe there was a significant struggle between the killer and the victim.
Cases like the armed robbery of The Singleton Store in 2003. Around $15,000 was stolen on April 11 of that year.
And a year-and-a-half later in Singleton, there was the mysterious disappearance of 19-year-old Carlos Rodriguez. He was last seen in early October of 2004, and has not been seen since.
"Time will not heal these wounds," said Sowell. "We will stay an active investigative agency on these cases."
Eakens is one of the lead investigators on the unsolved county cases. He says while crimes do occur in the county, he and his colleagues are always ready to check back on an old crime.
"New information comes to light," he said. "We solve a lot of cases here, current cases. We have plenty to do without looking back, but we don't ever really just file it away in a vault like some cold cases are."
So while lakes aren't being dredged on a daily basis, authorities are always digging for more information, hoping for the one clue that closes a case.
"There's somebody out there that's aware of these situations, and we need to have them arrested if possible and let them participate in the criminal justice system," said Sowell.
If you have information on any of these crimes, you're asked to call Grimes County's Crimestoppers at (936) 873-2000.
