LEE COUNTY, Fla.- The man accused of killing his ex-wife, Cape Coral teacher Amy Patterson, has pleaded guilty to her murder. Daniel Proctor accepted a plea deal in Lee County court this afternoon, but his deal is not set in stone. 

He would serve 25 years under that deal.

The state told Judge Margaret Steinbeck that Patterson's family didn't agree with the sentence they offered.

Since the family wasn't in court, the judge wants to hear from them before officially sentencing Proctor.

"I think it's an unfair position to put a trial court in, to say judge we want you to accept the plea," said Steinbeck.

WINK News spoke exclusively to Patterson's mom whose says her former son-in law deserves the worst.

"We didn't agree with 25 years, no. I think he should get life. He's just a cold hearted murderer. that's all there is to it," said LaDonna Salehi.

She says Patterson's death scarred the family for life. It took more than a year to find Patterson's body, only after Proctor led deputies to the crime scene.

"I'm going to reiterate the fact that he knew for a year what he had done with her body, and for a year, we suffered. I mean literally suffered. I mean nervous breakdowns, it put tremendous stress on the family. Tremendous stress," said Salehi.

Salehi hopes judge Steinbeck will give him at least 35 years. Now, Proctor still officially pleaded guilty.

But if the judge determines he deserves more time, that plea deal will be thrown out. Proctor then has the option to either accept a new plea deal, or go to trial. Proctor is already serving a life sentence in Alabama for grand theft.
