Alarming letter to Ind. mom: "We're watching your daughters"

GARY, Ind. - An Indiana mother received a letter from someone threatening to kidnap her daughters, prompting her to call police and lock her children inside their home, reports CBS Chicago.

"You have two lovely daughters... I and my friend have watched them ever since they moved in... almost had them on Thursday evening, will keep trying... Thank you!," the letter that arrived at Alfreda Murphy's Gary, Ind. home on Saturday read, in part.

There was no name attached to the postmarked letter and no signature included, only a warning about her two oldest daughters that reads, "We will get them."

CBS Chicago was there as Gary police took their first look at the letter, which includes details about when and where Murphy's children had played in the neighborhood just two days prior.

"They're sending letters saying that they're watching my kids and they almost had them this week," Murphy told the station.

She's now terrified to let her six children out of her sight.

The letter was postmarked June 6, and Gary police now have it as evidence as they work to track down who sent it. Alfreda Murphyand her family moved into the home just two months ago, CBS Chicago reported.
