Bones fans may finally be rid of serial killer Pelant (Andrew Leeds) but there may be another serial killer on the horizon.

Booth (David Boreanaz) killed Pelant in Monday night's episode of Bones, but the serial killer talked about another killer being out and on the loose. This killer - who is thus far unnamed - may become the new nemesis to Booth and Brennan (Emily Deschanel).

The new killer will not be as open and visible as Pelant, according to Bones executive producer Stephen Nathan.

"It's not going to be someone who is as visible," Nathan explained to TV Guide. "Pelant wanted to be known. The next person we meet, we won't necessarily meet. This is going to be somebody who values their anonymity far more than Pelant did."

In other Bones news, Boreanaz posted a tweet Tuesday in which he addressed rumors that he would be quitting the show at the end of the season.

"Why wld I "quit" a show I love?" he tweeted. "Keep it real I have a 'deal' . No reason to explain, as my love for ‪@BONESonFOX is a blessing. ‪#RaisetheBar."

The rumor began when RadarOnline published a story indicating that Boreanaz would not be continuing past season 9 of the show. The report claimed that Boreanaz was telling people that the current season was his last and that Fox might cancel the show if he were to leave.

Bones airs Mondays at 8 p.m. on Fox.
