St. Paul police: Man arrested after calling 911 to report killing his wife

A man was arrested for murder Tuesday after St. Paul police say he called 911 to report that he had killed his wife. 

Shortly after 3 a.m., Ramsey County dispatchers took a call from a 46-year-old man who told them he had shot his wife inside their home on the 30 block of Winnipeg Avenue West, according to the St. Paul Police Department. 

The man had made the call from outside the Ramsey County Law Enforcement Center, which is where officers located him and took him into custody. He was eventually arrested and booked into jail on suspicion of homicide. 

While investigators were talking to the suspect, officers went to the couple’s home on the 30 block of Winnipeg Street and found the man’s wife, a woman in her 40s, dead inside the home. She has been identified as Caitlin Aldridge, 41, of St. Paul. 

No motive has been determined, police said. Investigators are working to determine what happened in the moments before, during and after the woman was killed. 

The case remains under investigation.
