TROY, Mich. -- Madeline Kafoury was not just a receptionist at an accounting firm, but a mother, grandmother and the central figure in her family's life, her son said at the arraignment of the man charged with shooting her to death at her workplace on Monday.

Two other men were injured in the shooting that took place at the Gordon Advisors' Accounting Firm in Troy.

Anthony LaCalamita, 38, entered the 1301 Long Lake Crossings building on Long Lake Road just after 10 a.m. on Monday, armed with a 12-gauge shotgun, according to police.

The Oakland County Prosecutor's Office had issued a warrant for LaCalamita for the shooting.

He has been charged as follows:

Count 1: First-degree murder in the death of Madeline Kafoury
Count 2: Possession of a firearm in the commission of a felony
Count 3: Assault with intent to murder for the shooting of Paul Riva
Count 4: Possession of a firearm in the commission of a felony
Count 5: Assault with intent to murder for the shooting of Alan Steinberg
Count 6: Possession of a firearm in the commission of a felony
Count 7: Fleeing and eluding in the fourth degree

His arraignment was at 11 a.m. on Wednesday in Troy with Judge Michael Martone.

Because LaCalamita did not have representation, a not guilty plea was entered on his behalf. His preliminary examination was scheduled for April 19.

When LaCalamita was asked by Martone if he understood the charges and if he was aware that he could be sentenced to life in prison without the possibility of parole if convicted of first-degree murder, he responded, "Yes," to the series of questions posed by the judge.

Kafoury's family members sobbed in the courtroom while the charges were read.

"We're not even sure what to say right now. We're all still in shock with what's happened and it hasn't had time to sink in," Kafoury's son Charlie said through sobs outside the courtroom. "We want Alan and Paul, and everyone at Gordon Company that had to go through this horrific tragedy to know that our thoughts and prayers are with them. My mom may not be with us, but she will always be in our hearts. We want to thank everyone for their prayers and support."

On Monday, LaCalamita made his way to the second floor of the building and walked through the doors of Gordon Advisors' Accounting Firm, where he was laid off last week, according to former employees.

Police said LaCalamita entered the building with his weapon next to his body. Two employees who were exiting the building while he was walking in quickly called 911 from their vehicles.

Troy police detective Sgt. Barry Whiteside said LaCalamita walked by 63-year-old Madeline Kafoury, who was sitting at the receptionist desk, and asked her if Alan Steinberg wanted to get shot. Next LaCalamita entered his former boss's office and asked Steinberg if he wanted to get shot. Police said Steinberg made a move to step aside when LaCalamita fired.

Whiteside said LaCalamita went to Paul Riva's office, another former boss, just as Kafoury was walking out. Whiteside said LaCalamita shot Kafoury first, and then shot Riva. Both collapsed outside the office.

An employee told police they heard LaCalamita utter the words "Good-bye, Paul" as he walked out.

Kafoury, who later died at Beaumont Hospital in Royal Oak, had retired after working at the company for 20 years, but returned in January to help the firm through tax season.

Both men remain hospitalized at Beaumont Hospital. Steinberg, 48, of Bruce Township, is awake and communicating, while Riva, 48, of Sterling Heights, is still unconscious, hospital officials said.

Emergency crews and Troy police officers immediately responded to the scene and, unsure of LaCalamita's whereabouts, they surrounded the building, searched the premises and evacuated employees to a neighboring building.

A Dexter resident driving on Interstate 75 called 911 after, he said, he spotted the car LaCalamita was believed to be driving.

Authorities caught up with the 2007 silver Ford Fusion in Bay City. After a 30-minute chase, LaCalamita was apprehended and police seized a shotgun from inside the car, according to police.

LaCalamita was arrested and taken to the Genessee County Jail, then to the Troy Police Department.

Troy police officers learned that LaCalamita just separated from his wife and moved out of their Novi home and into a Troy apartment.

Investigators searched the apartment and Dumpster located just outside and found evidence they believe links LaCalamita to the shooting.

Inside the Dumpster investigators found practice targets that were shot up, which leads them to believe he was practicing with the gun before the shooting, according to Troy police.

Investigators also found a box that read "gun case." The items from the Dumpster were taken away in evidence bags, as well as undisclosed evidence from inside the apartment.

Police made contact with LaCalamita's wife, who told authorities that her husband suffers from bipolar disorder, has been hospitalized several times with mental health issues and has attempted suicide.

Investigators learned that LaCalamita recently bought a weapon at Target Sports, and recently applied for a concealed weapons permit, but was denied.

On Tuesday, Local 4 learned more about LaCalamita's past and what he wanted to do with his future.

Rescue 4 obtained LaCalamita's resume and found that he had been a student in the Catholic seminary.

From 1998 to 2000, LaCalamita was employed as a math and computer teacher at Notre Dame Preparatory School in Pontiac.

A school official told Local 4 that the LaCalamita he knows is a holy and good man.

"He was a wonderful guy, very religious. He basically handled all of our religious ceremonies for the school," the Rev. Lean M. Olszamowski said. "He was just a wonderful guy. We were very pleased with his performance and was very sorry that he left us."

Olszamowski added that he was overwhelmed after hearing about LaCalamita.

"It was nothing like he was when he was here at the school," Olszamowski said of the shooting.

Notre Dame will held a mass at the school on Wednesday to remember the victims of the shooting.

Troy police said LaCalamita remains in jail under close supervision, and will be arraigned on Wednesday.
