Hunterdon County Prosecutor Anthony Kearns said that there was "no further evidence other than coincidence" that Baker was involved in either case. Kearns has said authorities do not suspect foul play in Majoras' disappearance.
Local residents said they, too, believed Baker's connection was simply a tragic coincidence.
"Everybody around here knows it's not a possibility," said Joe Ujj, who is helping to coordinate volunteer search efforts for Majoras. "I work with Adam and have known him since high school. It's not that type of thing. I don't know how else to say it."
Baker, authorities said, called people from the bar to ask why Majoras had not returned home Saturday morning. Anderson's death was believed by authorities to be an accident, according to The Inquirer's article from the time. Efforts to reach investigators from that case were unsuccessful.
For those who knew Anderson and Majoras, like Tony Artur, 43, a Lambertville resident, the search for Majoras has carried greater emotional weight because of the memory of Anderson's death.
"There's a sense for people who've been around long enough, even if it's unspoken, you can see it in people's eyes," he said. "It's like, 'Oh, no, this is happening again.' "
Ujj said Baker and Majoras' mother have been staying together in private since the weekend.
"It's just too much," he said. "They don't know what to do."
Ujj was coordinating upward of 130 volunteers to help police canvas sections of Lambertville on Tuesday. More than 150 people turned out on Monday, he said.
He established a "Find Sarah Majoras" Facebook page Sunday night, he said. People were also sharing information on Twitter with the hashtag #findsarah.
On Tuesday, authorities released surveillance photos taken from the bridge that they say show Majoras crossing into Lambertville. In a statement, Kearns said authorities hope the photos may trigger someone's memory.
He added that helicopter and ground searches of Lambertville continued, and dive teams again searched the canal.
