The Pinellas County Sheriff's Office said Monday that 46-year-old David R. Perry recently returned to Florida after abruptly going to New York the weekend the 35-year-old Rothwell disappeared.

They say detectives asked him Sunday to submit a DNA sample, but he refused.

Rothwell, who enrolled at the Pinellas Police Academy in St. Petersburg, was last seen March 12.

Donna Scharrett is the last person known to see Rothwell after a girls' night. A grocery store surveillance camera caught a glimpse of both women as they grabbed pizzas for dinner, reported CBS affiliate WTSP.

The next morning the two went to yoga and then had lunch at Chili's. That was the last time Scharrett saw her friend.

Scharret told WTSP that Rothwell had plans to go home and break up with her boyfriend David Perry, whom she had tried to break up with before unsuccessfully.

Indian Rocks Beach detectives say Rothwell was sharing an apartment with Perry who was a retired corrections officer, the station reported.

Anyone with information in the case is asked to contact the Pinellas County Sheriff's Office at 727-582-6200
