UPDATE: Family Desperate For Answers: Where Is Tom Doolan?

NEW LONDON, CT —Tom Doolan was living in a sober house in New London. Then one day, the 59-year-old was gone.

It's been almost a month since his family has had contact with him. His daughter Paige Knobel said she is certain he would not miss his grandson's birthday. Nor would he miss Christmas with her, his son-in-law and grand kids. And short of walking every street in New London searching, Knobel and other family have taken to social media in their search, calling everyone who knows him, calling hospitals across the state, contacting rehab centers, even jails. There's been no sign of him. Knobel has talked to police and filed a missing person's report she said.

But on Monday, Dec. 30, three days after this story was published, police have issued a Silver Alert.

"None of this makes any sense. My dad would have never missed his grandsons' birthday or Christmas with his daughter and grandsons and son in law," she wrote on Facebook.

Knobel's mother Suzanne Cordova last saw Doolan on Thanksgiving. In an interview with Patch, Knobel said she last saw him Dec. 1. He had been "living in the Berkeley Street sober house but thought he was getting kicked out and then he just vanished and left his things." She said she's not been permitted to have his belongings "to maybe get answers." When last she spoke with him he appeared "manic frantic and just out right delusional and making absolutely no sense."

Knobel, whose husband is in the military and just recently returned home from a deployment, said that her father last used his state and Social Security electronic benefits cards around Dec. 4 and has not been heard from or seen since.

"I'm trying to hold it all together and it's hard," she wrote.

Doolan grew up in Colchester. Most of the family is in the area. Cordova said she and Doolan broke up 20 years ago but have remained friends.

Doolan has substance abuse problems and has a criminal record with a conviction for breach of peace and assault. But Cordova says that, "regardless of his past this is very out of character for Tom. He’s never went this long not contacting his daughter. Ever. We need help. Please, I’m begging for my daughter's heart is breaking."

Cordova told Patch that, "As someone who’s watched Tom's ups and downs for many years, decades, this just isn’t him. So yes, we’re suspicious for sure."

"All his belongings are still there, it seems he just simply disappeared because he told one guy he was going to see a friend in a trailer/camper down the road. And never came back. We’ve searched for said camper trailer and found nothing," Cordova explained.

"Tom is a fantastic story teller, as most addicts are but he was clean. He has never gone more then two or three days without contact with Paige. Or me sometimes. We’ve talked to his visiting nurse and his doctors, there’s been no contact. Whenever Tom has been admitted to anywhere, historically, he always has nurses or doctors call Paige to tell her where he is. She’s a mess. Her dad is everything to her. And I can’t stress enough that this isn’t Tom. Not even in the worst of his addiction in the past he would never not contact her. We need help."
