2 Killed, Partner Sought : Crime: Police search for ex-CEO, believed to have gone on a daylong shooting spree. Another business associate is wounded in Santa Ana; police warn a third man.

Police are searching for a man they believe went on a daylong shooting spree Monday, killing a woman and a business partner in San Bernardino County and critically wounding another partner in a parking structure here.

The suspect, 56-year-old John S. Hanna of Upland, is considered armed and dangerous, according to Santa Ana Police Lt. Robert Helton.

The Santa Ana shooting occurred just before noon in the 1500 block of North Tustin. Police said Greg Lawyer, 51, was shot twice in the upper torso. He was taken to Western Medical Center-Santa Ana, where he was reported in critical but stable condition, undergoing surgery Monday night.

The shooting took place outside Lawyer’s office at North Canadian Marketing, a subsidiary of the Calgary-based North Canadian Resources Inc., which builds electrical power stations.

Lawyer, Hanna and the others had been partners in another venture called North American Cogeneration Inc., which Helton described as “failing.” That corporation was suspended by the California Secretary of State on July 1, 1991, on the recommendation of the State Franchise Tax Board. The company listed Hanna as its chief executive officer.

Witnesses told police that Hanna came to North Canadian’s suite and asked for Lawyer. The two men walked from the office to an adjoining parking structure, where the sound of loud voices was followed by several shots. Lawyer was carried to the building’s lobby, where he was treated by paramedics.

Lawyer gave Santa Ana police the names of several other partners in the venture who he said might be in danger.

“Those were only two names he was able to mention to us in the emergency room, just before surgery,” Helton said.

Authorities in several jurisdictions around Southern California then attempted to contact the partners.

Using witness reports of Hanna’s license plate, police in Upland went to Hanna’s home, where a woman’s body was discovered. She had been shot, police said. They would not say whether the victim was Hanna’s wife.

Police tried unsuccessfully to reach another of Hanna’s business partners, 54-year-old Herbert Roy Ratch. Ratch’s wife told police that she dropped him off Monday morning for a meeting with Hanna in Corona.

San Bernardino sheriff’s investigators in Chino Hills found Ratch’s body just after noon in a grain storage lot in the 17000 block of Pomona Rincon Road in Chino.

“The evidence indicates that Ratch had been murdered,” said Det. John Ginter, probably some time after 10 a.m. Ginter would not say whether Ratch had been shot.

Helton said Santa Ana police were able to reach another business associate, Bernard F. Kolanowski, in Carlsbad, to let him know about the earlier shootings.

Just after 2 p.m., Kolanowski said he heard a shot at the front of his home, in the area of his locked gate in the 800 block of Heather Lane, and immediately called police.

Kolanowski, 57, said he saw Hanna walk past his window and ring his doorbell, according to Carlsbad Police Lt. Greg K. Fried. Kolanowski then said he hid in his garage, awaiting police. Fried said that as police arrived, a second shot was heard from the rear of the house, but they did not find Hanna.

Kolanowski told police that he was due in court today in Riverside in a case involving Hanna.

North American Cogeneration had a Santa Ana mailing address, Helton said, but the company was actually based in Corona.

Hanna is described as white, 6 feet tall, 170 pounds with gray hair. He was last seen driving a dark blue, 1991 Buick, California license plate number 3CTP294.
