Police were called about 9:55 a.m. to assist other law enforcement agencies with a man who was threatening to commit suicide, police Master Sgt. Gary Knight said.

A woman told police Eckstein was at the Sooner State Pawn Shop, 1009 SW 59, and was sending her text messages threatening to kill himself, according to the incident report.

The woman told officers Eckstein bought a shotgun and ammunition. Officers tracked Eckstein's cellphone to a church near SW 39 and S Pennsylvania Avenue. Officers called the tactical team to set up a perimeter.

When team members tried to make contact with Eckstein, they found him dead inside his vehicle, according to the report.
