Steven Matula has posted a number of details about the investigation to Facebook, including that he believes his 24-year-old sister and David Roe did not get into a physical fight because he said no bruises or scratches were found on Roe. Steven Matula also said investigators did not find his sister's blood in Roe's vehicle.
Mandy Matula has been missing since early Thursday. David Roe, also 24, of Victoria, Minn., was called by detectives for questioning in her disappearance, and on Friday afternoon he went to the Eden Prairie police department, but he shot himself outside the building. He died before police could question him.
The Hennepin County medical examiner confirmed Roe died from a self-inflicted gunshot wound to the head.
Steven Matula also writes on Facebook that the note Roe left behind directed police to check Roe's cell phone, in which he left a goodbye message for his family. Steven Matula also notes that Roe's laptop did not offer details about his sister's whereabouts, and police are seeking a warrant to scour Roe's Facebook and social media accounts.
The search for Mandy Matula continues after volunteer searches over the weekend did not turn up fruitful new leads.
Dozens of volunteers and police searched Miller Park in Eden Prairie and in areas of Stearns County. Investigators said cell phone records indicate Roe was in that area after he was last seen with Matula, FOX 9 reported.
On Saturday, searchers found an unspent bullet near Miller Park that police are calling possible evidence in the case, although investigators did not say if the caliber of the bullet matched the handgun that Roe used to shoot himself, the Star Tribune reports.
The Star Tribune notes that weekend searches for two other missing women, Kira Trevino of St. Paul and Danielle Jelinek of Oakdale, also did not turn up new leads.
