Sister Of Missing Indiana Mother Kelly Armstrong Calls For Help

The sister of a missing mother of one from Kokomo, Ind., says she fears for her sister's safety and is appealing to the public for help.

The missing woman, Kelly Armstrong, 27, has not been seen for about six weeks, said her sister, Shelly Rush of Logansport.

"We have gone several weeks in the past without talking, so I thought maybe she is just doing her thing, working, whatever," Rush told The Huffington Post. "But as time went on with no contact, I realized something was wrong."

Armstrong and her boyfriend, Travis Funke, live together with their eighteen-month-old child. According to Rush, she has reached out to Funke several times but has been unable to get a definitive answer as to her sister's whereabouts.

"Her boyfriend always has an excuse," Rush said. "He will say she is out and about with so-and-so, and he can't get a hold of them, or that she is working, but he's not sure where. It is a different answer every time."

After visiting her sister's local hangouts and talking to her friends and neighbors, Rush came to the conclusion that nobody has seen Armstrong in about six weeks. Rush said that she sent the Kokomo Police Department to her sister's home to conduct a welfare check. When they were unable to make contact with Armstrong, Rush filed a missing person report.

"The police are over there now waiting on a search warrant because he is not answering the phone or door and they have a one-and-a-half-year-old baby," she said. "They're trying to figure out, because he is on house arrest, where he could have gone."

Calls made today by The Huffington Post to a number listed for Armstrong and Funke went unanswered.

Kokomo police declined to discuss the case.

"I don't have any information for you at all. I can't confirm anything at this point," Officer Dave Trine told The Huffington Post.

Armstrong has auburn hair and brown eyes. She is 5'2" tall and weighs approximately 120 pounds.

"My sister is very loved and missed," Rush said. "She is not one to go this long without reaching out to her family."

Anyone with information is asked to contact Kokomo police at 765-459-5101.
