COLUMBUS, Ohio - Police in Columbus are trying to find out who murdered a Youngstown man, and why.

Detectives have identified the victim of a Monday shooting death as 29-year-old Brian Austin Jr. of Youngstown.

A news release from the police department's homicide division says that Austin was found lying in the threshold of the doorway of a home at 1624 East 25th. Avenue.

Police say Austin was suffering from gunshot wounds.

Austin was pronounced dead shortly after police arrived at 1:48 p.m.  

Police say they have no obvious motive for the crime, and the release makes no mention of possible suspects.

Austin's mother Stacia Baxter, who lives in Youngstown, tells 21 news that she was not notified of her son's death until 11 p.m. Monday night.  

Baxter says police have not revealed to her any motive, but she believes that detectives may be coming to Youngstown as part of their investigation.

She says her son was visiting friends in Columbus, where he had previously attended Ohio State University studying to become a dentist. 

According to his mother, Austin never missed a day of school and was a member of the Young Scholars program.

He attended Volney Rogers in Youngstown, where he played little league football.

Austin also attended Chaney High School and graduated from Farrell High School, where he played volleyball.

Austin previously worked at Pepsi and the Joy Cone Company where he was a crew manager.

Columbus detectives are asking the public for information to help them solve the case.
