The mother of the man accused of killing sheriff's Sgt. Gary Morales has declined to comment but conveyed her condolences to his family.
"This is a very tragic situation," Charmaine Tisdale said Wednesday afternoon. "We are sickened over it. ... Our prayers are going out to that family and ours."
Tisdale said she has been advised not to speak with anyone about the situation and asked for privacy for her family.
Her 25-year-old son, Eriese Tisdale, remains in a Martin County Jail charged with first-degree murder in the Feb. 28 shooting death of Morales.
"I can't imagine what she is feeling," said Michelle Boyer, who lives in the Tisdales' former Port St. Lucie home. "She was very nice, and religious."
Boyer said she never saw Eriese Tisdale, who co-owned the home with his mother before they lost it in a foreclosure.
The Tisdales purchased the home at 1065 S.W. Ingrassina Ave. for $208,000 in 2007, according to mortgage papers and arrest records. After a Sept. 19, 2012, foreclosure, William and Diane Boyer bought it for $115,000.
At some point, Eriese Tisdale moved to a Mura Drive apartment in southern Fort Pierce.
He was going to a store about a block away from that apartment when Morales stopped him, according to the arrest affadavit. Tisdale said he drove away because he was frightened by the armed deputy and contended Morales bumped his vehicle, according to his arrest report.
Tisdale allegedly got out of his car and shot Morales several times at point-blank range, including at least once in the head, through the driver side window while the deputy was sitting in his patrol car with his gun holstered.
Tisdale acknowledged he killed Morales but claimed it was in self defense, according to investigators and the arrest affidavit.
Sheriff Ken Mascara said the apartment gave a glimpse "into the state of mind this guy had because there's guns in there, more ammunition ... It looks like he was not gainfully employed. There was drugs in there."
