GARDEN CITY - A Boise man sought in connection with a shooting earlier this month in Garden City turned himself in to authorities Monday night.

Mykle Don Blumenshine Jr., 28, had been identified by investigators as person of interest in the October 20 shooting of Paul Wyatt Russell Jr., 30 of Meridian.

Blumenshine surrendered to police at a home in the 10,000 block of Fox Brush Court in Ada County. He was arrested and booked into the Ada County Jail on an agent's warrant. He has not yet been charged in connection to Russell's death.

The Ada County coroner said Russell died of a single gunshot wound to the head.

The shooting happened at around 7:48 p.m. the intersection of West 39th and Stockton streets, just behind the fire station on Chinden Boulevard.

Elena Pena, 27, was arrested October 21 - along with her boyfriend, 34-year-old Lyle Croson.

Pena was taken into custody on a felony charge of aiding and abetting aggravated battery, while Croson was arrested on a warrant for violating his felony probation. He has not yet been charged in connection to the shooting.

Garden City Police say they will ask the prosecutor's office to bring homicide charges against all three. Investigators say no other suspects in the shooting are believed to be at large.

“Blumenshine Jr’s arrest was a major step towards closure in this homicide investigation," Police Chief Rick Allen said in a statement. "There is still a lot of work to be done but we believe we have all the suspects involved in this homicide in custody.”
