Bittrolff could be the Torso killer, with how very close the bodies were found to his residence.....if its the case, did Bittrolff evolve into the GB4 killings, let me explain.
The first 3 women, Colleen, Rita & Sandra were all murdered within several months of each other, & from everything ive read, he killed them within hours of picking them up. I dont think much planning went into the first 3 killings, he knew he wanted to rape/kill, but it seems he was just starting out & had not thought out his plans too much.
Then in 2000 & 2003, Valerie Mack & Jessica Taylors torsos were found several miles from Bittrolffs residence, & could not be identified.....were we seeing a serial killer evolving?
Rita's body was discovered Nov 2nd, 1993. Sandra's body was in the woods for several days before being discovered Nov 21st, 1993. Colleen was reported missing Jan 6th, 1994 & her body was found on Jan 30th, 1994.
All 3 early victims were found within days of their murders, Colleen being the longest, 24 days. Was the killer frustrated with how fast his victims were being discovered & decided to start dismembering the bodies where it was difficult to identify?
A change of MO from the previous 3 victims.....& there are other victims as well before settling on GB4, but I wanted to focus on GB4. If its the same killer that was responsible for the first 3 victims, then turned to dismembering Valerie & Jessica & killing several others, he totally switched MO's again & decided to go online to find his victims. If it is the same killer, he definitely learned not to leave semen & any other evidence on the bodies with Valerie & Jessica.
From what ive read, Bittrolff had killed his victims within hours of picking them up, did he evolve into prolonging torture for several days with any of the GB4.....were the GB4 killed within hours of being picked up, or were they tortured for a day or so?
We know the sister of Mellissa was mentally tortured over the phone by LISK, & so were a few other friends of other GB4 victims.
The killer of GB4 seems so different from Bittrolff, at least from everything we have read/heard online....then again, serial killers can drastically change their methods.
