HOUSTON -

The Montgomery County Sheriff's Office is investigating two crimes against local senior citizens, a spokesperson for the agency said.

The crimes happened months apart, but the most recent incident was on September 16.

"From the initial information, they think it was two different groups or possibly different suspects (from the same group) doing the same thing," Lt. Dan Norris said.

In one case, the suspects gained access to the victim's home when he posed as a tree expert.

"He was showing me all the trees that were dangerous and he kept guiding me away from the house," resident Oel Kastner said.

While Kastner was distracted and kept busy in the back yard, his home in the Spring Ridge subdivision was burglarized on July 10.

Kastner, who describes himself "as closer to 80 than 70" believes he was followed home from a grocery store not far from I-45 and Rayford Rd. in Spring. He lost expensive heirloom rings and a coin collection.

"I lost 60 years of coin collecting that's where the injury is. The value of the coins is in the thousands but to lose your hobby is much more emotional," Kastner said.

More recently on Brook Hollow Drive further north, an 89-year-old woman was duped by someone who posed as a state official, concerned about nearby power lines. In a similar fashion, the woman was relieved of her valuables.

The Montgomery County Sheriff's Office recommends the same advice to all age groups: Don't answer the door to strangers, but let them know through a locked door that you are home. If necessary, call police.

If you have information about either crime call Montgomery County Crime Stoppers at 1-800-392-STOP.
