GRAPEVINE, Texas - The search for a a convicted sex offender who stabbed a Miami-Dade police officer with a broken pair of eyeglasses in Texas continued Wednesday night, according to authorities.
Surveillance video shows Alberto Morales leaving the parking lot of a Walmart in Grapevine, Texas, moments after the stabbing, authorities said.
The dark-colored video showed Morales outside the store in suburban Dallas as he walked away from a grey sport-utility vehicle. Police say Morales, 42, stabbed Miami-Dade police detective Jaime Pardinas four times while they stopped at the Walmart so another detective, David Carrero, could use the restroom.
Pardinas, 54, remained hospitalized at Parkland Memorial Hospital in Dallas on Wednesday after undergoing surgery. He is talking and is expected recover, Miami-Dade police sergeant Patricia Bimonte.
In 911 calls released Wednesday, Pardinas was heard breathing heavily as he told a dispatcher what happened.
"Where's the guy that stabbed you?" asked the operator.
"He ran," answered Pardinas.
"Where'd he go?" said the operator.
"I can't tell you," said Pardinas. "I've been stabbed in the neck. Subject is 5 feet 7 inches, 165 pounds, white Latin male named Alberto Morales. He's a schizophrenic."
Bimonte said up to 10 officers from Miami-Dade were expected to be in Dallas on Wednesday to assist with the search for Morales.
"We need to find this guy. I can't imagine that he has been able to get out of here. He's in a pair of shorts, he's in a T-shirt, he's got one shoe," said Bimonte.
Grapevine police spokesman Robert Eberling said authorities continue to search near the airport and will do so until they believe they should look elsewhere. He said the search covers "any place anybody can hide," including yards and drainage ditches.
The Texas Dept. of Public Safety is offering a $10,000 for information leading to Morales' arrest. Chris Heisler with the Honor Network said the reward would likely be increased.
Police say Morales has charges dating back to 1994.
Longtime Las Vegas defense attorney Marc Saggese, who represented Morales in a Nevada criminal case, said Tuesday that Morales claimed he suffered a severe brain injury when he was hit in the head with a baseball bat at age 17, and that he hears voices and has trouble controlling his impulses.
"He said that ever since that attack and subsequent surgeries he has been struggling with demons in his head," Saggese said.
While in a jail medical ward, Morales mutilated his genitals and scrawled words in blood on the wall. He underwent a psychological examination by doctors at a Nevada state mental hospital in Sparks, but he was found competent to stand trial, the attorney said.
Morales eventually pleaded guilty in 2008 to sexually assaulting a woman at an apartment blocks away from the Las Vegas Strip in 2003. The woman told police a man jumped from her closet in the middle of the night, held a gun to her face, blindfolded her, attacked her several times and left after telling her he would kill her if she called police, according to Clark County District Court documents.
Following his conviction in Las Vegas, Morales was sent to Florida to face prior charges, Las Vegas police Officer Laura Meltzer said.
Back in Miami, Morales was sentenced to 10 years in prison in December after pleading guilty to sexual battery with a deadly weapon, burglary with assault and kidnapping stemming from 2003. He broke into a Miami-area home, pulled out a butcher knife and raped two women, according to a police report.
