ROCHESTER, N.Y. -- A woman says she's positive she saw Trevyan Rowe standing on the wrong side of the railing as she drove across the bridge over the Genesee River downtown.

Rowe, whose body was pulled Sunday from the water, was spotted on Thursday morning by Kimberly Abramow, who says she won't soon forget what she saw.

Abramow, who did not want her face shown on TV, says she was driving east on Interstate 490 on her way to work. She was heading over the Frederick Douglass-Susan B. Anthony Bridge when she says she saw Rowe, who went missing from School No. 12 not long before that.

Abramow says the 14-year-old Rowe, who lived with autism, looked scared, so she promptly called 911 sometime between 8 and 8:15 a.m. Thursday. As the mother of a six- and 17-year-old, she says the look in the boy's eyes is something she'll never forget.

"It's just awful and I just feel so bad for that mother that she had to wait four days, and he was right where we said he was and that was the worst part," Abramow said.

"I don't know why he was on the bridge. What I feel is that, you know, I know he was upset and was running from school and maybe he got scared when he ended up on the expressway and all of these cars are coming at him at 60 miles per hour, you know? And he could have slipped. There was so much ice."

State police confirm they received several calls Thursday morning reporting the person on the bridge, but responding troopers found no one. It wasn't until this weekend when those 911 callers insisted the two incidents were related that police linked them and were able to locate the body in the water.
