PEORIA, Ill. -- Peoria police arrested a fifth teenager in connection with last week's homicide on Starr Street.
Authorities say he faces charges for allegedly threatening a teenager on Monday. Peoria County State's Attorney Jerry Brady says the 16-year-old remains in custody in juvenile detention pending a judges decision on whether or not he will be tried as an adult.
Brady would not confirm or deny whether or not the teenager who was allegedly threatened is a witness to the September 26 homicide on Starr Street.
Three suspects, Marquis Flora, Dionte Wells and Charles Smith, are students at Manual Academy and charged with first degree murder and armed robbery.
Authorities believe 15-year-old Smith fired the bullets that killed 54 year-old Michael Robinson and injured Perry Mollohan as they sat on the back porch of the residence at 2214 W. Starr.
As a result of the latest incident, there were additional police at Manual on Tuesday.
"We did have officers in the building working on their investigation, we are collaborating with Peoria Police in their ongoing investigation, separately there was also locker searches being done at Manual Academy," said District 150 Spokesman Chris Coplan.
Coplan says officers did not find anything in their search. He says the school was not on lockdown Tuesday but adds visitors and students were monitored as they passed through halls.
Peoria County State's Attorney says another person is under investigation in connection with the homicide.
