The man who police believe used a semi-automatic gun to kill the building manager at a Palo Alto senior-housing complex on Thursday before turning the gun on himself has been identified as Marc Alvin Miller, a resident whom one neighbor described as "disgruntled." The man he shot was identified by the Santa Clara County Coroner's Office as Vincent DePaul Collins, 70.
Collins had four gunshot wounds to the head and torso, according to the coroner's office. His cause of death was determined to be homicide.
Miller, 69, was found deceased with a single gunshot wound and the cause was determined to be suicide.
One resident said the shooting at the Alta Torre Apartments on Fabian Way may have been over a parking dispute.
In the days since the shooting, residents of the 56-unit apartment complex have been coming to terms with what happened.
"Everybody is very upset," Judy Jagerman, an Alta Torre resident, told the Weekly. "I can see it in their faces that people are sad."
She described Collins as a "wonderful person" who had at least one daughter and four grandchildren.
"It's such a tragedy," Jagerman said. "He had so much to live for."
Collins had been a resident manager at Alta Torre since it opened 2010, according to BRIDGE Housing. Some residents described him as "strict," and Jagerman acknowledged that he was "very strict and very precise." But he was a "happy and wonderful person who always smiled," she added.
"He was the best manager ever," she said. "He kept it so clean."
He had been her friend for five years. When Jagerman faced a crisis and lost her job, Collins told her to "trust in the process," she said. She posted those words in her apartment for encouragement, and she did find a job, she said.
Genrikh Geberger, another resident, said of Collins: "He was very careful -- very strong. I liked him. He kept the place clean. He was very thorough."
But resident Adassa Walker said she had a few run-ins with Collins. When her daughter gave her a plant for her birthday, Walker put it on the patio outside her apartment. It leaked a small amount of water and left a small stain, which made Collins very angry, she said.
Collins also made Walker move her car out of the garage and onto the street after it started leaking oil. Her daughter had the car fixed, but recently Collins said it was leaking again. Walker's daughter asked to leave the car in the garage with a pan underneath it until she could afford to get it fixed, but Collins had refused, she said.
Miller also had a dispute with Collins regarding his car, which Collins had banished from the apartment parking garage due to leaking oil, Walker said. She thinks that might have caused the shooting, she said.
Parking on the street is a hardship for older persons, Walker said. Often, it's difficult to find a parking space and then walk back to the complex. On-street cars also have to be moved every 72 hours.
Miller had spoken with Walker's daughter on a number of occasions. "He was really upset about his car, and it was going on for a while," Walker said of the disagreement with Collins.
Susan Johnson, executive vice president at BRIDGE Housing, said Collins was "well-loved by residents, and highly respected by colleagues -- a kind, lovely person who approached each day with a positive outlook."
"Vincent took pride in maintaining the building so it always looked brand new," Johnson said in a statement. "He will be greatly missed."
Last Thursday, Palo Alto firefighters responded to a 911 call from the complex shortly after 3 p.m. A resident reported that a man in the building's elevator needed medical assistance. They found found Miller with a handgun in his lap and an apparent gunshot wound to the head.
About 10 minutes later, police officers who were summoned to the scene found a second body in the manager's office on the first floor. The man, now identified as Collins, had been shot multiple times.
The woman who dialed 911 on Thursday told the Weekly that she had been waiting for the elevator with her husband. The woman lives in the building and did not want to be identified by name.
"The elevator opened and I saw someone had collapsed inside," the woman told the Weekly. "He was lying on his left side. I saw there was blood near his head."
On Friday, several residents of the 56-unit complex said they knew Miller. One resident, who has been living at Alta Torre for five years, called Miller "disgruntled."
Geberger said that his and Miller's apartments are on the same floor, but that he did not know him well. "We were not friends," he said, although they would exchange pleasantries.
Another resident, who lives a floor below Miller and who frequently saw him around the complex, described him as "lonely." But though she said Miller lived alone, she didn't think there was anything out of the ordinary about him.
She said she had seen Miller at about 2 p.m. Thursday, roughly an hour before police received the 911 call, and nothing seemed amiss. She said she had just walked into the building when she saw Miller walking out of the elevator, which she was preparing to enter.
"We just said, 'Hi. How are you?' like neighbors typically do," the woman told the Weekly.
The Thursday shootings brought a heavy police presence to a bustling south Palo Alto block that also includes Loral Space Systems and the Oshman Family Jewish Community Center. About a dozen police cruisers and the department's mobile command center swarmed the scene. For hours after the shootings, the main entrances to Alta Torre and the Jewish Community Center were cordoned off while officers collected evidence.
Yet despite the flurry of activity, police almost immediately determined that there was no danger to the public. At about 4:45, police said they had recovered the weapon and that they didn't believe any suspects remained at large.
Since the shooting, Palo Alto officers have been interviewing residents and people who know Miller and Collins in hopes of determining the motive, police said Saturday.
On Friday, BRIDGE officials sent a letter to residents expressing their condolences and concern. They planned to hold a meeting about the tragedy, Jagerman said.
Alta Torre, developed by the nonprofit BRIDGE housing and opened in 2010, consists of one-bedroom apartments for low-income seniors. BRIDGE spokesperson Lyn Hikida said the organization's top concern is "for the well-being of our employees and residents."
"We are reaching out directly to staff and Alta Torre residents to provide them with support in the wake of this tragedy," Hikida said.
