An 'illegal immigrant' allegedly murdered his roommates as they begged for their lives after they evicted him. .
Luis Perez, who federal authorities believe is in the US illegally has been charged in the fatal shooting of former roommates Steven Marler, 38, and 23-year-old Aaron Hampton at their Springfield home on November 1.
A day later, Perez shot dead Sabrina Starr, 21, whose Missouri home he moved into after his first victims threw him out, according to charging documents.
Two other people were wounded but survived. Perez, 23, faces eight other felony counts in the shootings.
Aaron Anderson, 19, told investigators that he was waiting with Starr in an SUV outside Hampton and Marler's home when Perez shot them.
He said he was on the phone with Perez at the time and that he could hear the victims 'begging for their lives'.
Anderson was charged as an accomplice with two counts of first-degree murder in those killings and three other felonies.
Police also said Perez's girlfriend, Dalia Garcia, arrived on a bus from New Jersey on Friday and helped to burn evidence.
After the first shootings, Anderson, Perez and Starr drove to Starr's home, and police said she was shot six times there on Friday.
A relative found her body the following day. No other details of that killing have been revealed.
The probable cause statement doesn't list a motive in any of the shootings, although Perez and Anderson had recently been kicked out of Hampton and Marler's home.
