DENVER -- The man accused of stalking and killing a Wesleyan University student from Colorado turned himself in late Thursday, ending a national manhunt that began Wednesday afternoon.

Stephen Morgan, 29, called police from a convenience store in Meriden, Conn., about 10 miles from the bookstore on the Wesleyan campus, where Johanna Justin-Jinich was shot multiple times at point-blank range.

"He started walking around the store, bought a drink, he checked the newspapers, and then he asked me to use the phone," said Sonia Rodriguez, a clerk at the store.

Rodriguez said he tried to dial, but was unable, so she had to help him call police, not knowing who he was. She thought his car had broken down.

Police said Morgan, a former Navy sailor, had no identification on him when he was taken into custody, but that he gave police the Social Security number that would identify him as Morgan, according to sister station WSFB.com.

Morgan was arraigned Friday in Middletown Superior Court. His bond was increased at $15 million

Police had interviewed Morgan outside the bookstore Wednesday without realizing he was a suspect. An official with knowledge of the investigation told The Associated Press that police stopped Morgan shortly after the shooting, spoke to him and let him go.

Later, when police confiscated Morgan's car, they found a journal in which he spelled out a plan to rape and kill Justin-Jinich before going on a campus shooting spree, said the official, who spoke on the condition of anonymity because the case is under investigation.

Wesleyan officials said police told them that Morgan targeted Wesleyan students and Jews in his journals. Justin-Jinich, of Timnath, Colo., came from a Jewish family, and her grandmother was a Holocaust survivor.

Morgan, who is from Boulder, Colo., was driving a car with Colorado plates when he surrendered, police said. It's unclear where he was headed, or if he had even planned to leave the state. Police had issued an alert for him in New York, Massachusetts and Colorado, saying he had connections in all three states.

Morgan was enrolled at the University of Colorado in 2007, according to CU records. Prior to that he lived in Colorado Springs from 2002-2005 and owned a home there, the Colorado Springs Gazette reported.

Victim Felt Threatened By Suspect, According To Police Reports

Justin-Jinich, who is from Tinmath, Colo, is being remembered by friends in Northern Colorado as a remarkably compassionate woman.

"She was a beautiful person, but it was also the beauty of her soul shining through that made her that beautiful," said Adele Eastman, a friend and former teacher.

Justin-Jinich is survived by her mother, Ingrid, her father, Daniel, and her sister, Leah, a student at Carleton College in Northfield, Minn.

Justin-Jinich was a 21-year-old junior at Wesleyan but knew Morgan from a six-week summer course they took together at New York University in 2007, police said. A New York City police report showed that Morgan threatened the victim in 2007 when they were both attending NYU.

Justin-Jinich filed a harassment complaint against him on July 10, 2007, claiming that he was calling her repeatedly and sent her insulting e-mails for at least a week.

In one e-mail, Morgan allegedly said Justin-Jinich was "going to have a lot more problems down the road." According to the report filed with New York police, Justin-Jinich said she felt "scared" and "threatened" by Morgan's e-mails.

Morgan had apparently already left the city at the time the complaint was filed and was not arrested.

Justin-Jinich would have graduated next year from Wesleyan, a private liberal arts school in central Connecticut with about 3,000 undergraduate and graduate students.

She was working at the Red and Black Cafe inside Broad Street Books when the gunman walked up to her and shot her several times. She was pronounced dead at a hospital.

WSFB reported that Wednesday was Justin-Jinich's day off, but that she had switched her schedule.

Suspect's Journal Threatens To Make Wesleyan 'The Jewish Columbine'

Police said earlier the suspect may have been targeting the university and the Jewish community.

Police with dogs and armed with assault rifles swarmed nearby streets looking for a suspect early Wednesday afternoon and asked Wesleyan students to stay indoors. But after reassuring residents later in the afternoon that there was no threat to the public, police issued new warnings Wednesday night, telling residents and students to stay inside and be "extra vigilant."

Police Lt. Margaret Liseo said evidence uncovered at the scene "heightened our level of concern."

"We just want to get the message out there to be extra vigilant," she said. "This individual is armed and dangerous, and we want to be sure public safety is our top priority."

Police said Morgan may have been staying at a Middlefield motel for a couple of days prior to the crime and among the items found in his room was a journal where he wrote that he hoped to make Wesleyan "the Jewish Columbine."

Justin-Jinich's former stepmother, Karin Radcliffe, said she came from a Jewish family.

"She was just a wonderful kid, very smart, very loving," Radcliffe said.

Suspect's Family Speaks

Diana Morgan, Stephen Morgan's younger sister, offered a statement Thursday afternoon on behalf of her family.

"We're shocked and sickened by the tragedy in Middletown, and our heartfelt condolences go out to the friends and family of the victim," she said.

"We love you. We will support you in any way," she said.

Greg Morgan said his brother has not shown anti-Semitism in the past. "My brother was a very sweet person and had a big heart and I hope he's OK," he said.

Wesleyan Asks Students To Be Alert

As a result of the threat documented in Morgan's journal, Middletown's only synagogue, Congregation Adath Israel, was closed.

University officials offered counseling Wednesday night and issued security alerts for students.

"Although he apparently had a direct link to the victim but no other connection to the Wesleyan community, we have now been made aware that he expressed threats in his personal journals toward Wesleyan and/or its Jewish students. All students are urged to remain vigilant and to stay indoors. Additional security has been deployed accordingly," a statement posted on the Wesleyan Web site said.

"This is a devastating loss for Johanna's family, friends, and for the entire Wesleyan Community," the university said in an earlier statement. "Our hearts go out to all those who grieve for Johanna, and we hope all can find comfort in the support of friends, teachers and classmates."

Authorities said there were several witnesses to the shooting, and police found a wig used by the gunman and a weapon at the bookstore. Liseo said authorities haven't confirmed that it was the weapon used in the shooting.

The shooting and manhunt forced police to order hundreds of college students gathered nearby for Wesleyan's annual Spring Fling concerts to seek refuge. The concerts, held annually to allow students to blow off steam before spring semester finals, were canceled Wednesday.

Police officers were at the scene quickly because the station is less than two blocks away and officers were undergoing SWAT team training.

Outside the bookstore, several young women clustered outside the police line, crying. They said they were friends of the victim but would not talk to a reporter.

Other students called the shooting "tragic."

"We went from the height of our mood where everyone was really happy the semester was over to we don't even know what to think," said Darien Combs, a 20-year-old sophomore from Denver. "We're just processing."

Campus, Community Reacts

Middletown Mayor Sebastian Giuliano extended the city's thoughts and prayers to Justin-Jinich's mother, father and sister.

"Personally, as a parent of college-aged children, this has to be every parent's worst nightmare," he said. "You send them away to school and all you think about every day is 'Are they OK?' Our full support is with Wesleyan to help ensure the safety of their students."

Students struggled to cope with the campus shooting on Thursday, with those who knew Justin-Jinich describing her as a passionate writer who was well-liked.

Wesleyan student Sydney Howe said Justin-Jinich trained her to work as a server at the bookstore café where Justin-Jinich was shot.

"She was really fun, a really nice person, really welcoming to everyone that came into the cafe," she said. "She was a really amazing person, so nice when I started. She taught me everything about working at the cafe."

Student David Burke said he first met Justin-Jinich freshman year in their dorm.

He said at the time of the shooting, he and Justin-Jinich only lived two doors apart in an off-campus high-rise.

"She was a very quiet girl, kept to herself, did a lot of homework. She went to her dorm, the library and to work," he said.

Wesleyan President Michael Roth extended condolences to Justin-Jinich's family.

"This is a tragic time for them, and for all of us in the Wesleyan community. We are all deeply saddened and shocked by this event," he said.

Box lunches of roasted vegetables, tuna fish or cheese sandwiches were being delivered to students in dorms while Wesleyan's cafeteria remained closed on Thursday.

"We're supposed to do some work, but really I just keep checking my e-mail and checking on friends and letting people from home know that I'm OK," said freshman Christina Yow, of China. "Anything to distract."

School officials said counseling services were being made available to students, faculty and staff.

Final exams are scheduled to begin at the school next week.
