Police are releasing new details in their investigation for a missing 24-year-old Eden Prairie woman whose ex-boyfriend committed suicide outside of the Eden Prairie police station.
According to Eden Prairie Police, ballistics testing confirms that markings on an unfired round of ammunition discovered Saturday indicate it was at some point in the chamber of the gun Matula's ex-boyfriend, David Roe, used to shoot himself.
The unfired round of ammunition was found near Victory Lutheran Church in Eden Prairie.
There were reports of gunfire near Victory church. According to police, several calls were made reporting gunfire.
Police say a DNA analysis has revealed the presence of Matula's DNA in a blood sample from a jacket found in Roe's vehicle.
Police say David Roe, legally purchased a gun in Carver County on April 27 less than a week before she disappeared.
Matula has been missing since leaving her family's home late Wednesday. She was last seen with Roe.
Roe had agreed to speak with police about Matula's disappearance before he shot himself. He left a note behind, which had no mention of Matula.
The note directed police to a short video on his cell phone, which was a goodbye to his family.
Additional details on the note have not been released. Roe was pronounced dead Friday.
Police repeated surface checks on lakes in Eden Prairie and continued to follow up on leads Tuesday.
Evidence from Roe's vehicle, cell phone, computer and his home and financial records have led police to search in targeted areas.
Police held a news conference Monday about the case, saying that authorities have searched Chanhassen, Victoria, northwest Stearns County and Hennepin County.
Those are the areas where Roe had his cell phone signal ping off towers, according to police.
Police say they've confirmed Roe stopped for gas at around 4 a.m. Thursday in Maple Grove.
Meanwhile, numerous tips about Matula have been flooding into police.
Police recommend that Eden Prairie residents interested in helping should search their own property and neighborhoods, including nearby wooded areas. While searching, police are reminding the public to be safe and respectful of private property.
Anyone with information on Matula's whereabouts, or who may have seen her with Roe on Wednesday is asked to call the Eden Prairie Police Department at 952-949-6200.
Matula and Roe graduated from Eden Prairie High School in 2007. The Duluth News Tribune reported that Matula played softball at the University of Minnesota Duluth from 2008 to 2011.
In 2007, Roe was arrested in a stalking incident in Hennepin County, police said. But he was never criminally charged.
Matula has been a part-time seasonal worker with Eden Prairie's Park Maintenance Division since 2007.
