Missoula police reopened a 1974 cold case in April, involving the murder of a 5-year-old girl. Since then, they received several tips from dozens of people who called to help.

Missoula police detectives say there's still a lot of emotion involved with the disappearance and the stabbing death of Siobhan McGuinness. Police do not believe McGuinness was taken by someone she knew, based on the tips they received.

Missoula police say since they reopened McGuinness' murder case when they received between 70 and 80 phone calls from all over the country.

"Through those tips we were able to figure out a better location and a better time frame of when Siobhan became missing and where she became missing from," said Dept. Dean Chrestenson of the Missoula Police Dept.  

Police say the abduction happened on the evening of February 5th 1974 when McGuinness was walking home alone. She was last seen on the corner of Worden and North 2nd Street West in Missoula. And two days later her body was found in Turah. Police say McGuinness was molested and stabbed to death. One of the tips they received is from a woman who used to live in Turah.

"Could not remember the color but she said she saw a vehicle stop right at that intersection, right directly where the culvert was where Siobhan's body was found," said Chrestenson.

Police also say a tip came in about a woman who lived near McGuinness. This woman heard a little girl scream from a car the day McGuinness went missing. She heard the scream at about 6:00 p.m. which is about the time police believe McGuinness was abducted.

"She didn't go out at the time to see the car, she didn't even really know a the time that Siobhan was being abducted, but she did hear that and later reported it to a friend, who then, after all these years called me when she found out we reopened the case," Chrestenson said.  

Police say investigators working on the case at the time did everything they could with the tools available to them. Police looked at everyone who may have been associated with McGuinness but to this day there's no name to match the DNA in evidence.
