Gunshots rang out from a Minneapolis sign company where police say a gunman fatally shot four and injured four others before killing himself Thursday afternoon.
Employees at Accent Signage Systems on Friday said they believed the shooter to be John Andrew Engeldinger, 36, of Minneapolis. Police did not confirm the identification, but they had searched a home connected to Engeldinger on Thursday night.
The gunman died of a self-inflicted gunshot wound inside the building, according to Minneapolis police. Police radio traffic during the incident indicated the killer had been fired from Accent earlier in the day.
Reuven Rahamim, founder and president of Accent Signage Systems, was shot to death in the attack.
On Friday, UPS confirmed one of their drivers, Keith Basinski, was killed in the shooting.
Other company executives were wounded. Eric Rivers remains in critical condition with gunshot wounds; John Souter, has been upgraded to serious condition.
A third injured victim, who was not identified, remains in critical condition, and the fourth was treated and released, according to a hospital spokeswoman.
When the shooting broke out Thursday, people fled from the building in panic. Joe Sedlachek, who lives near the office, came out of his home and called to the employees to ask what was happening. "But they weren't in any mood to answer," he said. "They were obviously very frightened."
"We do have several victims inside that are dead," said Deputy Police Chief Kris Arneson during a Thursday evening news conference two blocks from the business. A news release late Thursday night confirmed four victims in addition to the shooter.
None of the victims' names were immediately released. Identities will be released by the Hennepin County Medical Examiner's Office along with exact causes of death after their investigation is complete.
Sedlachek said he heard five gunshots late Thursday afternoon. "I knew right away they were gunshots," the Vietnam War veteran said. "They weren't firecrackers."
He went out to his deck and saw a man, then a woman, then two more women running from the building. One fell down, got up and kept running, Sedlachek said.
About five minutes later, two police squad cars arrived, and officers ran inside the loading bay, where Sedlachek believes the shots came from.
Several employees stood at each door, urging officers inside as more showed up, he said.
Accent Signage Systems' website lists Reuven Rahamim, 61, as the company's founder and owner. Sedlachek said he's good friends with Rahamim.
"Really, everybody thinks so highly of him," he said. "I know two things: His car is still here, and his wife was crying."
Sedlachek said the owner's son also works for the business. "Really good, good neighbors," he said.
At the home that was searched Thursday night -- the address listed on Engeldinger's voter registration -- neighbors said the occupant, a single man, had been arrested outside last week. He was put in a squad car and kicked the window out, they said.
Thursday's shooting occurred in a largely residential area just west of downtown Minneapolis near Interstate 394. Eight Accent Signage Systems employees were later seen standing in a prayer circle near the scene. Afterwards, they declined to comment on the shooting.
Mayor R.T. Rybak said the shooting happened at a "close-knit" and "true family business."
Accent Signage Systems was incorporated in 1986 by Rahamim, an Israeli immigrant, and it employed 28 people as of July, according to a feature on the business in Finance & Commerce, a local business publication.
The company developed a patented technology for producing signs in Braille and had licensed out the technology to companies in 38 countries, the newspaper said.
