St. Paul police are still investigating the "suspicious" death of a 25-year-old man found earlier this week in his home.

Police were called to a house in the 400 block of Bellows Street on the city's West Side around 1 a.m. Monday on a report of an unresponsive man.

Police reports identify the man as Brandon J. Horst. According to county property records, Horst owns the home along with Heather Horst, who contacted police.

Horst was found inside the home, said Howie Padilla, a police spokesman. Horst's autopsy is scheduled for Tuesday, he said. No further details were provided.

As of Tuesday morning, no arrests have been made as investigators try to determine how Horst died.

Several neighbors said they hadn't heard anything that morning before emergency personnel arrived. The couple who lived in the home kept mostly to themselves, neighbors said.
