Kansas City, Mo. ? Kansas City police have been working in a wooded area near the home of a baby that has been missing for two weeks.

The Kansas City Star reports that crime scene technicians worked Tuesday in the area a few blocks from the home where the parents of Lisa Irwin reported their 10-month-old daughter missing Oct. 4.

Also Tuesday, police in Riley County, Kan., said they were investigating a report of two women in their 20s who raised suspicions because they were with a baby resembling Lisa. Capt. Kurt Moldrup said someone called police to say the women left “in a suspicious” manner, but he didn’t elaborate.

He said his department notified other agencies in the area to look for the women’s vehicle, a small black car with Missouri plates.
