APOPKA, Fla. - A man who opened fire at a crowded Easter party remains at large Tuesday.
Apopka police said Wilfred Gregory, 33, cut off his GPS monitor after pulling the trigger Sunday, and then took off.
Now, police said they are questioning the owner of a company contracted to monitor GPS devices, including the one Gregory was wearing.
Apopka police said the owner of the company, Marcel Aponte, waited almost 12 hours to tell them he had a key piece of evidence.
"We're still very concerned about everyone's safety," said Apopka Officer Ed Chittenden.
Police said Gregory shot Calvin Johnson in the back and in the head during an Easter party near Alonzo Williams Park.
Officers said they thought they had him cornered at his family's home on 10th Street, but he wasn't there.
On Monday, police said they found out Aponte hid the fact that his private GPS monitoring company was watching Gregory, and that the suspect cut off his tracker not long after the shooting.
"Nothing was reported to law enforcement," said Chittenden.
Police said they found out six hours later that Gregory had cut his bracelet.
Police and Aponte searched for it and came up empty. They said Aponte went back without them and took the device.
"It's frustrating for law enforcement to have this piece of evidence that's now missing, and this person took this home," said Chittenden.
WFTV caught up with Aponte after he was questioned by detectives and asked him, "Were you tampering with evidence?”
Aponte replied, "No comment."
Detectives said they are deciding whether to charge Aponte.
