DNA test results lead to arrests for murder and rape

LAKE CHARLES, LA (KPLC) - On March 16th the body of 56 year old Darrell Lynn Schaub was found behind the Parkway Motel just outside of DeQuincy. The body was under a mattress behind the motel where Schaub had been staying for about a month. His elderly mother pleaded for anyone with information to come forward.   "That's the only son I had. Please if anybody knows anything, come tell."

It turns out the man they now believe killed Schaub and took his car and credit cards has been in jail all along. He's 29 year old Jon Boo Dickerson of DeQuincy, arrested by police there for burglary and criminal damage to property. Now, almost five months since Schaub's death, Sheriff Tony Mancuso says they've linked Dickerson to the murder. "We were able to obtain some evidence from the vehicle and through our DNA analyst we were able to confirm that it was the victim's blood on our suspect's clothing."

Mancuso credits DeQuincy police with keeping Dickerson's shoes that he says had Schaub's blood on them. And the sheriff believes there will be more cases solved more quickly now that they can do DNA testing locally at the regional lab. "Before if we didn't have blood from a suspect and a crime scene or victim, we could only link them if we had the two together in house. Now we can do our in house plus search throughout the United States."

Mancuso says not having to wait for results from out of town labs will eliminate delays that sometimes take 3, 4 or 5 years.

The sheriff says DNA testing also resulted in the arrest of Jonathan Frank for a rape that occurred 15 years ago.  Frank allegedly raped a woman in an apartment on Iris Street in 1994.  Officials say Frank has a lengthy criminal history and was already in jail when his DNA was linked to the rape case.  Mancuso spoke to the victim who now lives out of state.
